30cc custom homelite engine

[SUPERFORMIAN]

If you were to run a nitro engine without a chassis, it'd be a total nightmare...

[kolbpilot]

Thanks. I really need to learn how to rewind that spring for I've bought 3 weedeaters now for pull cord reasons only. I always like engines of all sorts & have always looked at that little 26 cc engine thinking what else it could do. And also its design life, for a throw away engine, I'll bet it'll last longer than people have patience. Of course, souping 'em up changes things.

[chipbreakr]

@kolbpilot

I have built engines for people that have lasted for years. The key is to mix your oil 6 to 8 oz. per gallon. Gives better protection . I actually have a 4 stroke lawnmower that I use to mow a hillside that I burn the same mix in. The engine has out lasted the mower deck. It doesn't smoke or foul plugs either .

[kolbpilot]

Being the airplane nut I am, I see a future for my Homelite engine swinging a small propeller for shits & grins on a static display. For now though, I'll just dream about it.

[kolbpilot]

How would you rate these throw away engines ? My first '94 Homelite weedeater 26 cc (USA?) ran every season for 11 years when the pull cord broke & I gave up on the recoil spring. Foolishly I threw it away. My 2nd one was very similar & this one I have after its cord broke. My latest Homelite is still a 26 cc (new weedeater) but has a made in China, low emission (lean jetted carb.) engine. I've had no problems in the 1 season I've been running the same engined blower.

[chipbreakr]

@kolbpilot The older homelites are the best for rc use. If you up the compression , do some port work and some other tricks , you can have a great engine for little to nothing if you can do your own work on it. I have rewound many pullstarter springs . If your spring is broke , I have a spare to 2 . If it just needs rewound I can do that also.

[tubefed420]

@chipbreakr , whats your starter spring trick. I fight them all the time in chainsaws.

[chipbreakr]

@tubefed420

On trimmers , I just put the notch on the spring in the slot and wind it. No trick really

[tubefed420]

@chipbreakr Must be weaker springs in the string trimmer starters. But thanks for the tip.

[kolbpilot]

@chipbreakr Thanks for the info. I now realize my older Homelite is a 25 cc model. I ordered a Zama adjustable carb for it & the whole affair is now powering my 26 in. Huffy mountain bike. I'm impressed that a little engine like that can get my 185 lbs. (& the 45 lb. bike) up to 25 mph. My new moped but a little more versatile really.

[TOPGEARisC00L]

were do you get the carbys from ?

[chipbreakr]

@TOPGEARisC00L

Find them every now and then on ebay and message boards

[christhetromboneguy]

damn son how did ya manage to build that contraption(pretty cool)?



[chipbreakr]

@christhetromboneguy

Been building them for boats for years

[richardarichter123]

sweet engine

[F4k3rg0pr0]

hello do yo uknow where i could get one of the water pumps i need one for my boat and i wish to know where you got yours thanks

[chipbreakr]

@F4k3rg0pr0

They are vacuum operated fuel pumps, most lawnmower shops carry them and you can find them on ebay .

[F4k3rg0pr0]

@chipbreakr can you make a video how to install them please

[chipbreakr]

@F4k3rg0pr0

Sorry I don't have any video of installing a engine . Do a search on the web , there should be something out there

[F4k3rg0pr0]

@chipbreakr can you make a video just showing the engine 360 nad explaining where the pump conects

[cpw80]

man that thing sound friggin awesome :o)

[thisguy324]

Whats the purpose of modifing a weed eater motor?

[chipbreakr]

@thisguy324

My engines are used for rc boats over 4ft. long. The air cooled engines I build can be used on scooters and bicyles

[balls2yourface]

Put the outlet from the water cooling off the header into the exhaust pipe

[chipbreakr]

@balls2yourface

You can do that , but it reduces the performance slightly .

[pivotboy63]

is there a muffler or just the expansion chamber?

[chipbreakr]

@pivotboy63

Just the tuned pipe

[jojomcc1000]

hi, i have 5 Homelite trimmers. How did you mount the exhaust

[chipbreakr]

@jojomcc1000 bolts on

[rcboatdriver1234]

 i likey

[theplatypus3]

what did it run off of nitro-methane?

[chipbreakr]

@theplatypus3

regular pump gas 87 octane with 8 oz. of oil mixed to a gallon.

[spitzification14]

@chipbreakr man you should look for a source of gasoline that is pure( without ethanol mixed into it) ethanol is not good for 2 strokes it develops a sludge over time that clogs carbs and deteriorates rubber gaskets and fuel lines or any thing rubber it touches in the carb and engine

[ilgopeds4378]

nice work good craftsmenship

[KrankieV2]

even water cooled. that is sweet.

[th19940305]

Damn thats a nice one

[mag2395]

bro where did you get all those upgrade parts from

[chipbreakr]

@mag2395

Made them

[rgdukeman]

what was so special about that besides it being brand new??

[chipbreakr]

@rgdukeman

If you know anything about a Homelite trimmer engine , you know they have half cranks in them . If you look closely , you"ll see there is a bearing on the back side of the engine . I modified the block and the crank on the engine to make it a full crank engine . There are only 3 of these known , and I built all 3 . So, that is what"s special and it's modified to run at higher rpm than a regular homelite .

[fluberhaben]

where did you get that pipe?

[chipbreakr]

@fluberhaben

Made it .

[rrjhs199516]

dude thats sick

[chipbreakr]

All of my videos of engines are after they have been modified and running them for the first time to check them out .

[shrimp909]

boo who... go move to California you hippie

[emtrixdk]

home made engine?

[bod93]

that sounds nice

[chipbreakr]

you'd need a pump ,radiator and some way to machine the cylinder[s] to make a waterjacket for it . Alot of expense and time involved .

[chipbreakr]

I wouldn't try it , a lot more heat and pressure , plus you might need a thermostat .

[chipbreakr]

In r/c boat you can have the water force fed from the rudder or run a vacuum operated fuel pump that is connected to the engine block to pump the water.

[MRdirtnap09]

what pumps the water threw the head??? i see u use a hose for testing purposes, but when those motors are in rc machines what do you use as a pump??

[2combast]

sick

[sledneckf5]

how much does a tuned pipe cost

[chipbreakr]

when I used to make them I sold them for $80,00 . Check on ebay , you can find them on there pretty cheap sometimes

[lukestuffy]

On some of them, it sounds like you've lightened the fly wheel. Then do you just re balance the thing? Do you explain any of this in detail anywhere? Let me know if I'm not intruding on your secrets.

[chipbreakr]

I grind down the fan blades on the flywheel. You have to be careful not to remove to much material , as it will weaken the flywheel., then I rebalance it . You don't want to do this mod if you aren't watercooling the head .

[pimpinpenz]

what if u water cool and leave it big?

[chipbreakr]

you can do that also

[victorrobles11]

tuff dude

[swarne8]

nice work! you can make exhaust pipes from scratch with simple formulas for u guys askin'

[chipbreakr]

This was a "one of" engine it had a custom full crank in it that I made. A regular full mod 30cc with pipe and engine mounts is $375.00 , if you furnish a good repairable engine $275.00 I won't be building any until this fall.

[dalejrroxx]

do u make the piston's or buy them.

[chipbreakr]

stock piston that I modify

[dalejrroxx]

how much wouls it be to biuld one like that.

[chipbreakr]

I made it

[chiefbrightwell]

where did you get your exhaust pipe from?

[pow0006]

thanks and sounds great!

[chipbreakr]

Take a stock engine and put it in a boat and then take a modded engine you will see a big differencein speed and power

[pow0006]

is there is any real power coming from these mods, if so how much

[chipbreakr]

read the comments above your , it explains the pipe.

[Nuggerz]

I hope that pipe works...what formula did you use for the specs on making that pipe?

[chipbreakr]

I roll them by hand out of 22 ga. sheet metal. You make a pattern for the front cone and one for the rear cone. I use silver solder to connect the seams and then weld the 2 cones together ,add a 1/2" pipe for the stinger and a 7/8" pipe for the header .

[pixuma]

Awesome! how do you make it fit onto the exhaust port, being that they're oval shaped, and how do you measure the exhaust port accurately? Thanks a bunch!

[chipbreakr]

Take your box muffler apart and remove the plate the is at the exhaust opening in the muffler , It has 2 holes and the exact opening that you will need to make a new exhaust manifold with , just measure it and you got it.

[pixuma]

ok, i have yet another question!

how do you get the cones so perfectly round? i have only basic hand tools and no money to buy slip rolls.

also, could you describe the header construction? i just cant see how it goes from a ovalish hole to a round pipe.

 Thanks! (again)

a vid on all this stuff would make my day(if you can)

[chipbreakr]

You have to have to take your time and don't try to to much metal at a time. Make small gradual bends until you make the cone. . You need and lathe and mill to make a aluminium billet exhaust manifold . If you don't have access to them it ain't going to happen .

[pixuma]

hi, i'm wondering if you could give an outline of how you make you're pipes, (how to use java pipe, but mostly how you roll the sheet metal

[geowal19]

have you made that cylinder if so how?

[chipbreakr]

The cylinder is a homelite cylinder. I have a fixture that I use in my lathe to turn down the top 5 fins on the cylinder. Once you remove the fins you can make a waterjacket [either round or square] to fit over the cylinder and drill and tap 2 - 8x32 holes in the top to attach the jacket. Put 2- 10x32 holes in the jacket for the water to run in and out of the jacket. you can buy 2 water fittings to connect the water lines to .

[sideshow45]

how much would that pipe be???

[ryanheilmann]

well, i just waNTED TO WORK ON IT AND GET IT RUNNIN BUT I DONT THINK ITS WORTH IT

[chipbreakr]

that all depends on how much compression the engine has and what you want to do with it

[chipbreakr]

sure have , a long time ago , echos where a great r/c boat engine

[ryanheilmann]

well i have one it needs a new gas tank has brown recluses all in it you think its worth fixin oh yeah it is clogged up to

[ryanheilmann]

have you ever done any work on echos

[triz250rtecatedude]

how much did that cost to make

[chipbreakr]

I don't make the full crank version like this anymore . A regular full mod with this waterjacket would cost 250.00 without the pipe . I mod mostly zenoah now .

[chipbreakr]

buy a new recoil starter, it's easier than trying to fix the old one

[ryanheilmann]

i have a promblem on my huquvava 325 e tech the starter rope ciol has a plastic peice the attaches to a metal peice the metal peice has a rod that runes throught the engine and turns the flywheel but i attached it but the fly wheel does not turn but i did find a metal peice that was broke ive never done any work on these engines before but this one is a real pain in the but

[chipbreakr]

The 254 plugs work fine for me. I have a fixture I made for my lathe that has a offset hole in it that makes setting the crank up to grind the pin a lot easier .

[sdvten]

I'll have to try some 254 plugs. I take it you lighten your flywheels. What balancer do you use to balance them after lightening?

[chipbreakr]

I made a balancing fixture , and use a old crankshaft that I modified to static balance the flywheel .

[chipbreakr]

I use a autolite 254 sparkplug , I have a few 167 carbs , but you can find them on ebay from time to time . Is the crank you are making forged or just made from one piece of steel? Both work fine, just make sure you harden the rod pin .

[sdvten]

Do you get any radio interference with the 254plug? The Autolite site says the 254 isn't a resistor plug. I've been running champions but got some Autolite 425 copper plugs to try which have a suppression core.

I'm not making the crank I'm going to modify a 25cc. I got a hold of an older 25cc for free and it has the old style forged crank. I'm going to have to grind it down to accept a 30cc rod/bearing because the old rod is thin.

[floydiangreen]

ok, but what does it do?, what is it used for?

[chipbreakr]

r/c boats

[sdvten]

What plug are you using? Also where did you get you 167 carbs? They stopped making them and I have a hard time finding them. I've been messing with Homelites a while now, but now since I have a machine shop at my disposal I'm making a Forged crank 25cc to go with my other WHH 30cc Pros. Awsome work.

[bigmodman]

oh... so it does have a coouple of cones inside the pipe???

well one is above the intake, and the other is below the exhaust.... if i do need a new head, could i use one from a 30cc motor???? nah i didnt use the degree wheel, cuz i did it when i was like 12 when i first got the motor. now i am 16 ad know a little more about this stuff.

also what do i need to run an alky carb on it? thanks

[chipbreakr]

It's one of my steel tuned pipes front cone , rear cone. If the place you put in the cylinder is below where the ring rides , it will be OK , if it above where the ring rides you'll need a new cylinder. If your not familiar with modding homies , you can do more harm than good. Did you use a degree wheel to set your ports?

[bigmodman]

is the pipe hollow or does it have staged cones in it?????

btw i seen your 25cc motor and want to do the same to it.... i have the intake port ported a bunch, and the exhaust as well, but when i did the porting i seemed to catch the cylinder wall with the bit,.. can i hone that out or do i need to just get a new sleeve????

[Savageowner610]

i have an old school homelite and im not sure what it is i.e what cc it is or year it was made in if you have any tips to find out or if you can help me (cause you probably know alot about homelites) let me know ill give you all the info i can. its going inot an airboat btw its about 5ftlong by 3ft wide its going to be alot of fun

thanks

[chipbreakr]

read the comments on this page for information on mods . you can remove the muffler and look in the exhaust port ,if the piston has 2 rings and the exhaust port doesn't have a divider in it , it;s a 30cc . Otherwise it's a 25cc.

[Savageowner610]

cool thanks alot!!

[Savageowner610]

um... the piston has 1 ring on it and there isnt a divider in the exhaust port.

[chipbreakr]

It could be a real old homie , some had a one ring piston on them. Look on the base of the cylinder and see if it says 30cc . If it's got a one piece crank , it would make a good modded engine .If the piston is 1 7/16" diameter , it's a30cc.

[Savageowner610]

ummm... where abouts do u live??

[chipbreakr]

In Cross Lanes ,WV

[Savageowner610]

If we shipped our homelite to you and sent money would you do some work on it?

[drumbum12345]

awesome, i have a homelite, just a q, hoy did you make the heatsink chrome

[chipbreakr]

waterjacket is billet aluminium that I wet sanded and then buffed to a chrome like finish,

[nahviiiii]

awesome sounds mate!

[chipbreakr]

Thanks,The old homelites had a sound of their own

[labreck12]

thats freakin sick man.. =o

[Dylan169113]

is that the origanl carb or custom and if so were did u get it? thanx

[chipbreakr]

It's a walbro 167a , it called a big bore . If your homelite is stock it will help some , if it's modified you can use a 167 or a 257 .They are on ebay all the time for around 25.00 to 35.00

[Dylan169113]

thanx i am planning on getting a chain saw engine so i wonder if this one would fit on one

[chipbreakr]

If your going to use a chainsaw engine you will ned a bigger carb . The carb I mentioned were for weedeater engines

[enjoi54321]

is that a chain saw enigine?

[chipbreakr]

no , it's a weedeater engine

[TommeyLeeReed]

Nice...

[stephshane1]

you could put that in pocket bike

[chipbreakr]

do a search on JAVA PIPE it's a program that gives you the dimensions you need to make your own pipe.

[fylerc1]

How did you make your muffler? Is it custom?

[fylerc1]

That's a beautiful engine. I am wondering how you made your muffler though. I've got a bike powered by a Homelite Super 2 chainsaw engine and would like to mod the muffler so that I don't bother my neighbors ever time I go for a ride.

[nitro74cs]

nice, is it watercooled?? if so is it home made and how does the waterpump works??

cheers

[chipbreakr]

As I stated below , I made all the aluminium parts and modded the engine. I've been building High Performance 2 cycle engines for over 10 yrs. The waterpump is a vacuum operated fuel pump .

[nitro74cs]

I see, keep up the good work m8. well done

[pantera132]

dude that thing is wicked snotty i love it

[calltollfree]

thats seriously the dopest vid on youtube!! nice work

[mnymatt]

ok calm down its not like its a video of heaven or somthing dam u about to have a heart atack

[calltollfree]

only cuz i did the same thing LOLOL i thot i was unique:(

[chipbreakr]

I make all my own parts. That's made from a block of aluminium.

[laina423]

where did ya get the water cooled head on that thing?  ...nice
