Racing Mower Engine

[alecm94]

how much was your cam? i have 12.5hp vanny, its in the process of gettin motor work

[ibuiltmineo1oo]

@alecm94 I don't remember. It was a long time ago.

[yeves1639]

can u tell me how u lowered it i am buildin a racing lawn mower to

[ibuiltmineo1oo]

@yeves1639 Basically The body is channeled,and lowered onto the axles. Its a combination of using a straight axle and channeling the body over it , moving the front end to a straight axle and attaching it to the front of the frame, and using smaller diameter tires.

Its a lot more work then it looks like. I had to sub frame the tranny mount back to the rear axle to keep flex out of the drive line so it did not throw the chain.

[musmn1313]

good info to know thanks

[musmn1313]

thanks anyhow but i wanna run 2 piece 4 bolt steel wheels with stretched turf masters ive been looking for the name of those tires forever

[ibuiltmineo1oo]

@musmn1313 Turf masters have the block tread, then the turf master 2 have the same block tread but are like dished out in the middle of the blocks. A lot better traction, but they wear faster then a regular TM. They are made by Carlson. Goodluck man!

[musmn1313]

thanks

[ibuiltmineo1oo]

@musmn1313

no problem! want to buy some burris rims with douglas dirt track tires on them?

[musmn1313]

where do you get the tires?

[ibuiltmineo1oo]

@

They are just regular ol Turf Master 2's. I think I got them at Walmart.

The wheels are Douglas Two piece aluminum Kart rims.

[ford1979truck]

omfg thats so sick . sounds amzing 

[jonycard1]

is that a harley davidson mikuni carb ?

[ibuiltmineo1oo]

@jonycard1

Its a 28mm roundslide off of an old suzuki snowmobile.

[tpvalley]

@ibuiltmineo1oo

are u using the cable from a twin carb setup?

was the suzuki a twin?

why not use both carbs and modify the manifold so there is a straight path for inlet gasses?

[ibuiltmineo1oo]

@tpvalley In this video it was jsut a test. The 2nd carb cable was still there. I eventually built a linkage to run it off the gas peddle. The reason I didnt run a 2nd carb was just simplicity. The boot bolted right to the intake, and one carb is easy to tune.

My new motor is a 44cid and I have one 44mm flat slide Kikuni on it. Its a beast!

[CAMOTRUCKN]

does the high compression give you more horsepower? is it done by shaving the head? and what kind of transaxle/gear box do you have? thanks

[ibuiltmineo1oo]

@CAMOTRUCKN Oh...the comression helps, but theres give and take. you shave the heads, and you get less combustion volume. Less air means less power. higher compression jsut means a more powerful burn at combustion. more torque.

i have custom pistons that raise the compression.

This one is running a straight axle and a 700 tranny. pretty standard racing mower setup, although i didn't realize it at the time!

[ibuiltmineo1oo]

@CAMOTRUCKN This was also running off a 30% nitro methane mixture. Get it started on gas, and then let it burn the nitro!

This was NOT a mower used in any serious racing like uslmra. just a street machine,and a toy.

[yamaharules163]

@ibuiltmineo1oo looks like you coulda made it legal to race though!

[ibuiltmineo1oo]

@yamaharules163 Yeah I think I could have, but when this mower was built I had no Idea what the racing ass. was, or any of the rules or anything.I just was trying to kick my buddies butt on our local track. None of us had any idea anyone else was doing this! We jsut got the idea, and built some mower, then built faster mowers!

[Tubbed69]

damn thats fuckin nasty.. i love the lumpy idle

[ibuiltmineo1oo]

@Tubbed69 Thanks! Thats my favorite part!

[brent3360]

how much the g team cam????

[ibuiltmineo1oo]

that was years and years ago. go to gteam and see for yourself

[MrRunescaper5]

sand the fly wheel its sckraping something

[ibuiltmineo1oo]

Its not scraping anything???? thats dumb.... thats the carb sucking on each intake cycle.

[k323r]

haha sand the fly wheel .thats so funny

[ibuiltmineo1oo]

@k323r

Sand the flywheel? you guys ever heard a roundslive carb idling without an aircleaner? you dont sand a cast flywheel? It a whole process to clearance the flywheel to the mags. and maybe you didnt notice, but there is no covers or anything else to rub on.. sand the fly wheel...lol!

[dirtscooterer06]

where do you find the light fly wheels for these mowers?

[ibuiltmineo1oo]

Mine's stock in this vid. If your a millionaire you can find a billet aluminum one from a mower racing company.

[joshmanfitone]

guy i kno has a takumsi 20 horse vtwin he stroked bored milled, and put a cam in to pump out 46 horse....he said the motor was expensive but well worth it

[ibuiltmineo1oo]

yeah, I think you can get like 4 grand into a big engine now a days! Shoot the flywheels is 400 bucks alone!

[BurningTirez]

i have a takumsi

[CSAKvids]

You mean a Tecumseh? lol

[domownator]

That will start a whole lot better if you will run your flywheel back to the compression stroke. Just turn it by hand or put your mower in gear and roll it backwards. If you put a billet wheel on then you will have to with the stock starter.

[leitzmanracing20]

where could i find one of those engines

[ibuiltmineo1oo]

ebay, Its just a briggs and stratton Vanguard.

[brent3360]

i would put that on a orginal lawnmower and jsut make it a little hotrod

[emeryjk]

sounds mean

[shicker88]

Looks like the great ham-beano from sandlot!

[ibuiltmineo1oo]

I would be severely pissed off if they did that to my video. I did not build this to race in races, so it has nothing to do with them.

[Mississippi1313]

@ibuiltmineo1oo

how much did the cam and billet rods cost?

im looking to modify my 18hp v twin vanguard

[qxvmx]

what carb is that it looks like a flat slide?

[ibuiltmineo1oo]

32.. mikuni flatslide off of a 250 suzuki snowmobile motor! Funny hting is all I had to do was go up 2 sizes in the main jet and it ran perfect! Dumb luck back then I guess.

[brent3360]

how much did it cost to build that beast sounds amazon nice job

[ibuiltmineo1oo]

This one was cheap. Scrap parts, used stuff off ebay, used motor, etc...lots of mistakes, and lots of elbow grease! Now a days its very expensive... Look at building a full out 125cc class race Kart, and thats about the cost of building a full USLMRA BP class racer. Too expensive for my blood now a days! I just terrorize the neighborhood now!

[blackbill44]

yes depending on your transmission. i suppose it would need ann overflow or a breather of some kind. i was just passing on what i heard. but i just got a honda rider and it absolutely will not race...

[blackbill44]

the transmisson trick is just get all the grease out of it and fill it with a gear type oil. as much as will feasibly fit in it to keep it from overheating . just a thought.

[ibuiltmineo1oo]

That's the Idea, but defiantly not the trick........

The trick is to keep all the oil from leaking past the grease seal of the input shaft and oiling your drive belt......

[blackbill44]

excellent race mower. my 95 craftsman is too nice to race. but maybe someday its a 15horse 6 speed. i really would like to do a pulley swap on it and the transmission oil trick. i mean oil in the tranny.

[ibuiltmineo1oo]

Dont mess with the pulleys unless its going to be a race machine. To dangerous to have the blades spinning faster!

[zenmaster1356]

whats the transmission oil trick? I just finished my racing mower.

[ibuiltmineo1oo]

keep in mind that the 'oil trick' that this guy is talking about is specificly for the 700 tranny. Federal Mogul has a replacement seal that fits the input and output shafts of the 700 and is an actual oil seal, and will keep the oil from getting on your belts.

[222lawnboy]

cool

[brent3360]

were can you get a bigger cam for a single cylinder

[camarolover1982]

ur welder and a grinder. u can make ur own

[sdylke]

screw driver plus cycloid = sparks

[Chevypower265]

Actually he was touching the battery charger right to the starter.

[mower05]

sounds like not enoughf gas to motor its boggging mine did the same u should call we can talk to me about it its 574-516-1035 call between 3:00 pm and 10:00 so ill be home!my names tyler a lady might awnser its my grandma

[yamaharules163]

nice, giving out your number on youtube...

[dumpsterdives]

That's what I was thinking lol.

[tocaracer06]

boy your a genius...your gonna get rickrolled like no other

[JUBALAKNE]

If you would do a 2 into 1 equal length pipe you would get more HP and would sound alot meaner..

not saying it don't sound good now, cause it does but you loseing all you scavenging doing it like that and thats HP

[WeSellYouTractors]

that is very true!!

[homeless51]

sweet sound

[refridga]

i got a 14 hp kohler

And i think my starter is startin to go out

[bigmaaack]

its beautiful :)

[musician1232]

HOW MANY HP IS THAT

[nismoskyline123]

that kinda sounds like my dads v8 truck

[14hpFme]

dude with 11hp briggs the way to get around your problem is to run power direct to the starter motor or check the fuse because my mower would not start so i checked the fuse and it was blowen not a big deal or check conections to the ignition if not your starter might be froze up

[holypit]

i have a 11hp briggs single with high compression the starter wont start the engine do u know how i could get it started

[jangoslayer]

actualy i had that same problem if the starter drags and it is hard to turn the flywheel that means you have to much compression clean the head(s) and remove muffler put your hand over carberator and breather (black tube if you have one) then ground jumper to frame and directly place positive on starter check for spark and it should start right up

also take apart starter and clean that also helped me!!

P.S. use wd-40 to clean head(s)

hope this helps it sure did for me

:)

[yamaharules163]

its probably not the compression. get the piston 1/4 from the tdc (or both valves closed) and then set your valve last at 004.

[Chevypower265]

Check your flywheel key, that also gives the type of problem your talking about, I highly doubt its to much compression.

[labreck12]

thanks for the inspiration.. i have a 16hp onan twin.. definately got my attention with this video!!

[justin5666123]

custom intake NICE!!!!!!!!!!!!!!!!!!!!!!!

[RedNeckBoy37]

How did you get a skidoo carburator on it???

[psyfertech]

did you just add straight pipes to it? cuz it sounds great

[ibuiltmineo1oo]

kindof.... I believe the trick to making a vtwin sound the best is LOOOOOONG straight pipes! the longer the better it will sound! This has like 4 feet of pipe on each side!

[psyfertech]

oh cool, yeah i might do this to the riding mower my uncle is giving me once we pull it out of the bushes, not sure what it is but its old and has them round headlights, im not gonna mow with it, just take the deck off and soup it up for like a universal tractor or somethin, lol

[6666665555551]

That thing sounds like it's got a Holly in it

[kdog122]

omg.. its a true redneck mobile a riding mower that sounds like it has a v8 you know whats up is that a Vtwin?

[ibuiltmineo1oo]

Ya, Its a 16hp vanguard twin.. and yeah its redneck, but Im not a redneck, just love to build cool shit! LOL!

[snowmobilerules]

that thing sounds great

[emo666steven]

do a burnout with that

thet wood be cool

[Motorfordtoyota]

that thing sounds like a v8 when reved, kool

[stunmunky]

Wait a minute thats a twin. My bad

[stunmunky]

I always wondered what a cammed up single cylinder sounded like!

[mudpuppy4life]

aftermacket cams? whats your power displacemnt

[JacknifeCreations]

you put an Intek on one of those F/X style mowers? i just GOTTA see that beast!

[JacknifeCreations]

you know one of these days you need to make an updated vid of your newest mower so people don't keep thinking you still have this one!

BTW, are you still on Heymow? haven't seen you on there in a while (i'm TheMowinCuban on there)

[ibuiltmineo1oo]

Yeah, I need to get the new mower out and dust it off! Its an early 60's craftsman, kinda like a mustang with a 44 cube briggs and the Techumseh tranny! LOL! I dont have aplace to di it since I moved 3 years ago! But we just bought a new house with a 40x60 shop, so next summer will be BACK into the FAST mowers!

[99minerkc]

Is it burning oil due to worn rings or did you just rebuild it?  The sound of the engine is great!

[ibuiltmineo1oo]

Its not burning oil, its just super super rich from that big ol carb on there!

It wasnt really rebuilt.. It was tore down and reassembled with higher quality parts, but not because it was wore out, just because i wanted a hotrod!

[JacknifeCreations]

this is just the sound of heaven! i need to start on my exhaust system for my 28 now that i have a welder

[ibuiltmineo1oo]

Just remember... The longer you can make them the better it will sound!

[paulbreor]

i have a single cyclinder 17

threw a rod and then i had to bust it open to replace the rod so i just went ahead and added billet parts and

rings/piston valves lifters cam and flywheel....

ohh yea

Great motor/Lawm mower

love your carb work...

[kingyamaha966]

how much was it to build

[labreck12]

omg that sounds amazing when revving

[Chevypower265]

I really love this thing! I know you sold it and its been rebuilt, but this video is just awsome! It has the best sounding set of pipes I've ever heard!

[ibuiltmineo1oo]

Ill tell you the secret to the sound, that noone else realises....... Length! the longer the better! Shhhhh..... secret!

[Chevypower265]

Thanks, For the tip!

[paulbreor]

glade i saw this reply cause i am curreny going to get ridd of my stock exhaust and add a pipe just didnt know how long it should be/

Yep, girls say the same thing, the longer the better! shhhh.....secret! o.o

[mudtruckman]

Nice!

[davem8888]

You do realise that its going to get fucking hot without the cowling onblowing air over the cylinders and with it running that rich

[ibuiltmineo1oo]

do you realise that this was just a startup to get the carb dialed in and to make a video, and not to run it, and that this video is like 6 years old, and that motor, and whole mower has been completely rebuilt atleast 5 times? Wow!

[dustinwaller87]

hey wat kinda performance parts do u have and if u do have some tell me where u got them

[KMScarboy]

is that a honda carb???

[ibuiltmineo1oo]

Well, Its a mikuni off of a suzuki snowmobile.

[bigandrich22]

oh and what did that motor originally come off of

[ibuiltmineo1oo]

Its a Vanguard 16hp V-Twin that was originally off of a lawnmower!

[bigandrich22]

is that an opposed twin or a v twin motor

[fpsraab]

its a v twin.....i work on these almost everyday.

[Assasin4179]

God bless harley davidson! :D

I think you need som serious tuning there..

I mean.. Jeez!

It sounds like a.. Boat?

Yet NICE! way better than my 4hk piece of shit build..

since i aint got the money, i had to build my own parts ;)

[ibuiltmineo1oo]

What? THis aint no funking Harley! And maybe it sounds like a....... lawnmower cause its a briggs and stratton engine? most Boats are twostroke and sound WAY diferent then this.....

[will79601]

sounds like a harley sounds freakin sweet sorry if I keep on I love the way it sounds what horse does it put out now?

[ibuiltmineo1oo]

cool man.... this is a pretty small was only a 16h to start motor. i bet it only gained a couple horse, but changed its power band a lot. if your looking for one, look for a 44 cube intek. they are ab out the best out there now. this videois pretty old, i dont even have this mower anymore!

[ibuiltmineo1oo]

Cam, good carb tune, and advanced timing.... port and polished heads, just good engine work, etc.....

[will79601]

I have never heard a mower run like that nice job!

[jordanfr13]

Mine is totally stock, but it makes tons of torq, and when I compression tested it, it showed 185 psi on both cylinders. Is that normal?

[NitroCaya]

the psi could be i bit to hight look up a manual on the internet or buy one from canadiantire

[jordanfr13]

Do you think the cam would make a noticible difference on a stock engine?

[ibuiltmineo1oo]

if you do one thing it should be a flywheel. that will be your biggest gain. itll give you the less rotationg mass, and also be able to adjust your timing, and be able to get some revs out of it! then jet your carb, and youd be surprised how she will run!

[jordanfr13]

I have been looking for a gteam cam for my engine just like this. Do they still sell them?

[ibuiltmineo1oo]

gteam racing. he can make you custom cams, or buy one off the shelf.

[JSTippie]

That is fucking sick dude!

[jordanfr13]

Is that the 30 cid model?

[kingyamaha966]

r u gona put twin carbs on that beast

[ibuiltmineo1oo]

Im going to try to put tin carbs on the big 50CID one i am building!

[Sephiroth5300]

I am in love with a lawnmower...lmao

[Zwitchau]

Fuck! man that is sick!

love it!

[showstopper540]

Ur having a little trouble cranking the engine, im a small engine mechanic in VA and i see this all the time. Adjust ur valves, set the cold lash to .004 (four thousandths / if the cam is stock, if not find the reccomended settings and adjust accordingly) on each valve at tdc. If the valve lash is too loose the engine will hold too much compression on the stoke and not crank over properly. With valves lift and duration operating correctly, the engine will crank easy and make optimum power.

-Jon

[ibuiltmineo1oo]

Theres WAY too much duration and lift in this custom cam to be holding compression!

Actually, in this video its because its running about 11:1 compression with the stock starter! this engine (after the billet flywheel was installed) would see almost 7000rpm!

[showstopper540]

Thats awesome, knowing those details its no wonder it had a little trouble cranking lol. Nice job, sounds great out the exhaust.

[ibuiltmineo1oo]

thanks man! there are some guys out there making some scerious HP from these motors!

[BeBe91760]

Nice engine good work

[petrolnut]

I want that sound on my mp3! Where do you get the gearbox from, i gotta 4hp briggs vertical shaft i'd like 2 get on a go kart but need a gearbox...

[ibuiltmineo1oo]

Its a bone stock peerless 700 5 speed from an old john deere rear engine i pulled out of a junkyard! I ran it all summer with no problems what so ever, but i also ran my belt a little easy so the belt would be the first thing to give. I think it saved the tranny from a lot of shock loads.

[ronurban]

hey umm do u have yahoo or any of that stuff i have a mower and i wanna build it up but i dont exactly know how im good with cars but by the loook of it ur good with mowers if u could just msg me on here and we can talk thanks

[shaunk132]

are you runing a muffler on it or just straight pipes?

thanks

[ibuiltmineo1oo]

straight 1.5 inch pipe.

[dangeroustoys56]

Sounds sweet- im building a modified murray- has a twin 18hp briggs with stright pipes ( i want em to exit near the back of the footrests eventually)- its basically stock( for now) other then the snap back throttle and golf kart wheels and pulleys- i plan on doing alot more to it ( lowering/widening/steering- adding a striaght rear axle) to make it more stable and faster/safer. Wicked cool tractor- too bad you dont have it anymore.

[PaterBoy17]

i have an oldish murry out in my shed, its like an early 90s model. culd i somehow suup it up to race?

[shaunk132]

sick sounding exhaust

[ibuiltmineo1oo]

Thanks man!

I thing the secret to the good sound is to have the pipes as long as you can get them.

The guy who owns the motor now has about 1.5 feet of pipe on it, and it just sounds like a straight pipe mower, instead of a sweet sounding V-Twin! LOL!

[shaunk132]

ya,i watch it every day it sounds so cool

[shaunk132]

oh! and what make of egine is that?

and the make of tractor?

ty

[ibuiltmineo1oo]

Its a vanguard by Briggs and stratton. 16hp, and the mower is a Murry chassis!

[shaunk132]

ty im looking out for one of those :)

[My56ChevyBelAir]

Man you got a killer mower there, to bad you don't still have it, i'll bet that mower really cooked!

[surfwes21]

i like the motor, check out my mower general lee. 17hp intek vtwin. rock on! hey how did u chnage the steering to the gokart steering?

[dansdashizzle522]

is that a vtwin or a single cylender

[ibuiltmineo1oo]

VAnguard 16hp v-twin

[86quadracer250]

did u buy that intake manifold or make it

also whats that about a 35-40mm mikuni?

[ibuiltmineo1oo]

Thats the stock intake manifold, and i portmatched it to the rubber intake boot that the carb stuffs into....... Its a 38mm mikuni straight off a an early 70's 250 suzuki snowmobile!

[86quadracer250]

deff a twin

notice the intake

[ibuiltmineo1oo]

I have a nice set of 38mm Mikuni flatslides for my new 44 CID briggs Intek! Its going to be a BEAST! GTeam racing!

[oxxonswe]

Hahaha sorry bro, but this sounds like an old boat xD ( maybe its the camera or something )

[ibuiltmineo1oo]

Oh yeah..... Its just a digital camera! LOL!

turn up your bass, and down the trebble to drown out the tranny whine, and the carb!

[fmftrx300ex]

i just got my snow blower back (my crazy 1) and it revs like way to high concidering how old it is im waitin for it to blow up lol ill post vid later 2night if i get some gas...its a gas guzzler

[fmftrx300ex]

thing sound sick nice goob

[quickwillis]

glad to see someone else turbocharging their v-twin mower. I've been doing it for a while. you can check out turbo murray search quick willis on youtube.

[offroad88]

Hey, Are you ever going to finish you sears build that you started after you sold the mtd shown in this video?

[ibuiltmineo1oo]

eventually!

Been busy having kids for the last 2 and a half years!

I guess Itll get dug outa the shed when the Boy is a little older!

[lolfetusfeet]

cool i got a race mower too. ill put the video on soon ...mice mower thou!!!!

[kingdork1212]

sweet mower...I have a vintage mower with an 18hp twin with side pipes and it's lowered and bored out just a side project for ice racing tho.

[ibuiltmineo1oo]

ive seen one Ice rcer. Looks pretty mean!

thoe tires are wicked on the ice racers!

mines just a side project, just for screwing around on.

[chevys10l4]

how can i make my hydrostatic trans mower fast

[ibuiltmineo1oo]

Roll it off a cliff.....Hydro's are internally regulated, the opnly real easy way would be to swap out a 6 speed..... Easy to do.

[fordhater207]

Is it possible to make an older opposed twin motor sound and perfrom like that?

[alexanalisa]

nice!

[ibuiltmineo1oo]

Thanks! This whole mower was sold years ago.... Ive moved on to a 44 cube Intek now!! LOL!

Going turbo and Megasquirt with that bad boy!

[hudson493]

all of yall are stupid i bet u didnt know it isnt the stock carb in the first it is a motorcycle carb

[ibuiltmineo1oo]

Duh...........

[wertheroriginal]

Man! That thing sounds awesome.

[ibuiltmineo1oo]

Thanks for the compliment!

[kasjv]

i have a 14 hp vanguard v twin engine and its hard to start i cleaned the carb in gunk and the fuel pump seems to be pumping gas any one no what else i can do and when i put eaither in the carb it starts but then dies out i hopeu guys can help ........DREAT VIDIO

[ibuiltmineo1oo]

some reason its not getting fuel....... start at the carb jet, and work your way back to the fuel tank cap.

[tltcrawlr]

ok thanks for the quick answer. Ya I already know about exploding 1st and 5th, I did that on my last racer(i was running a 1:2 ratio. That one was more of a learning base, this one I'm going all out.

[ibuiltmineo1oo]

I have a quick change gear set on the rear of my current one. Wit hte tentioner i have setup on there, i can go from a 32 tooth rear to 80 tooth rear, and it takes me about 5 minutes to change it out!
