Insanely Slow Idle on a Briggs and Stratton Engine

[seapeddler]

The Briggs engine is ingenious as it sucks only as much fuel as it needs. No overhead tank that can potentially flood engine big time if carb fails. Fixing a small engine costs millions today.

[Films4You]

Ticking Over

[engineprojects]

funny sound xd is someone climing on the wals whot an toilet destopeer=

[smallenginedude71]

that sounds like a hit and miss engine

or a putt putt engine that is sooooooo slow

[raptormaxx]

dont make things that reliable anymore?

[BUNCHofxs]

didnt the carbs on these models have a slit in the butterfly valve to? If it was completely closed it would die.

[BaberJacks]

must be a really good engine with really good compression

[utoobube]

Wow...now thats a tight engine.

[justingt3rs]

cuz it has no more compression

[semperfiedausten]

@justingt3rs

you're kidding right. im pretty sure an engine that can idle low has good compression

[radicalnegative1]

@justingt3rs Read the description.

[MrRazmushenriksson]

@justingt3rs An engine runs lower on high compression becuse of the pressure

[mozer30]

@MrRazmushenriksson i dont really understand your comment? please explain.My understanding is that an engine with higher compression will require a higher idle speed.Simply because the flywheel will need to carry more energy to overcome the compression stroke and not stall

[macgyverdroid]

@justingt3rs yup it has a very very low compression so you can run on a 300 or 400 rpm

[HedgehogOutdoors]

That's insane, is that about 200rpm?

[PNWtoyota]

lopin pretty hard lol

[canadacatalyst]

momentum!

[dawino6260]

My only question is how long did you have to warm it up to get it to idle that low?

[burnboy1212]

fap fap fap fap fap

[FoxxFire50]

bloop blubb blubb bloop blubb blubb bloop bloop blubb blubb bloop blubb blubb bloop bloop blubb blubb bloop blubb blubb bloop >_>

[dwmascho]

Sounds like an oil rig pump

[XxXJTHIBAULT116XxX]

thats sweet it sounds cammed

[5spd5thgen]

Briggs = old reliable!

[oldiron96]

Briggs will run for ever

[bubub56]

nice to see an iold piece of steel running now strap it on an old radio flyer wagon lol

[kibbalis]

good old heavy flywheels thats funny cool vid

[juniortore1]

Make sure you throttle it up every once and a while, because the little splasher on the piston rod will not splash oil to the piston and everything at that low of an RPM. Otherwise, that is awesome!

[mastersduhgree]

HHMMM.I think that engine is a bit low on compression(carbs working well tho).An engine that has factory spec compression wouldnt idle that low as it would not be able to follow through with the compression stroke at that RPM.

[KNGarver]

@fattony123082 Can't tell if stupid or never really seen or heard a real model t. The vehicle which does sound like this was before the t or a Trabant. Look up Trabant engine. Model t's sounded like ones today just slightly louder.

[woolliehead]

yup unbreakable till they chuck a rod out the side they are crap wouldn't own one

[RainJetSprinklers]

The Briggs engines with the up-draft carb, like this one, are pretty easy to make idle like this. The pulsa jet models are harder.

[TheTonihardy]

sure sign of a healthy engine, that thing needs a good home, find an old grinding wheel or a corn sheller or something thats low load so that thing can make it to a hundred years, good job fella

[MrGizmo757]

Oh yes. the unbreakable engine. :-)

[davcolli]

Those things run forever

[BigGreenTractor42]

Nothing stops a briggs

[fattony123082]

sounds like a model t

[dirtTdude]

sounds like a hit and miss... almost sounds like its hitting and missing too. wonder how slow you could get it to run with a bigger flywheel.... pretty cool man

[CtrolokDoncov]

damn the cam is rotating like 2.5 rp second

[tpearl209]

thats an old school briggs if you want to know just how old just just look at the first two numbers in the code

[travisjeanelle]

Thats dang near as low as I have my 28HP v twin B&S on my 2009 allis ac130 set at. Rocks the whole tractor but saves fuel

[jack9102]

8 people tried this but kept stalling their motors haha

[windsunvolts]

we used to have a ford workmaster tractor that would idle below 100 rpm-- that was the lowest marking on the gauge-- I believe it was hitting about 65 rpm. You could get off the tractor and if someone walked up to it, they would never know it was running!

[Theguido177]

Wouldnt mind using that engine on my lac xD

[AwsomeInEveryMinute]

lol it sounds like a hit and blow engine :P

[tiredowalkin]

haha, that's all the craz at engine shows, see how slow you can get them to run!! awesome!

[10yroldcarlover]

pour oil in it, see if it makes smoke rings

[Jasper1434]

240rpm ish?



[kendigjl]

I had an old Plymouth Valiant that would do the same thing after I turned the ignition off. 225 slant six, drove like a dream (*sniff*). Man I miss that car. Excuse me, I have to go cry now.

[EATSLEEPDRIVE2002]

@kendigjl lol that was probly carbon in the combustion chambers acting like spark plugs after you shut the ignition off...sounds like you got a lot of good miles out of it

[ww321]

We were fooling around with a really old ,I think 12hp B&S running total loss ignition and got it down to 45 rpm ! We were just dieing laughing waiting for it to miss ! Cool video ! :)

[maddogdan113]

doing what, 2 rpm? ;)

[erokn10]

nice work, that is not easy, especially with the condition thats in..lol sounds cool

[AlchemistHawk]

well built machines indeed 

[stevenblouis]

that is the slowest ive ever seen

[kfrederick09]

that is crazy i have over 12 various briggs motors an none of them idle that slow an sty running

[ZeeboLaywicker]

cool video..for those that dont know, just like cars, they gotta run fat on gas to idle like this..my bud has a 40 ford with a flathead..all original..when warmed up it ildes at like 400rpm or less..its so quiet you cant hear it run..but you could light the exhaust on fire with a match..:)

[michaelovitch]

@ZeeboLaywicker

yes but it's not good for the main bearings.

too much pressure on them

[NesteHukka2]

At that speed that knocking and rattle sound actually very cute ;D

[pkrieter]

I love the "boop,boop,boop" sound the engines make at low idle ! KEWL engine !



[davidrobert2007]

Beautiful - I love these old Briggs engines

[mikal1101]

you sir are the winner of the worlds slowest idle contest... at least in my eyes!!!

[yaris4fun]

boring

[Dualshock21]

only 2 hp?

[SaucyTuRkLeBiRd]

I was thinking that you would have a heavy enough flywheel to keep the momentum up but still have enough torque from each ignition of the fuel, excellent work! :)

[adamswindells1]

i want my Countax to do that but it needs a good refurb first & i havent got time to do it as its a working vehicle :P

[jwiss1995]

i have the same engine on a handiman rt tractor made by sears. what a good reliable engine. mine is black and has the rope pull start

[jwiss1995]

is that a model 14?

[radicalnegative1]

@jwiss1995 Yes it is. I think it's a late 50's model.

[10yroldcarlover]

@radicalnegative1 whats the estimation of the rpm? 75,60

[gumby1008]

its blowing bubbles!

[toyghgh]

thats awsome, here in the north west there is a vintage motorcycle club that has a idleing in gear contest, they prop up the rear wheel.(most euro n britt. models have a center belied kickstand which tips up the front unless u lean forward it lifts the rear) and engage the bike in first gear and get the bike to idle as slow and smoothly as possible. I think its really neat. fun fact. Peace

[92sonoma]

gotta love them old engines

[92sonoma]

nice, must be a really good engine. my 1965 allis chalmers B-10 tractor with the 10 hp will idle pretty much the same. It sat outside here in Indiana for about 20 years uncovered. I got it off an old couple. gas tank and carb was full of water, so cleaned and rebuilt the carb and cleaned and adjusted the points and it fired right up. It starts with just a tap of the button, easier than anything i ever seen

[Talon21500]

That puppy sounds like she's barely holding on!

[tylerspyler2]

I figured out it is around 240 rpm, nice. My jeep will idle at 250-300 but I have to make it do that.

[callmeshane303]

My 45 cubic inch Harley would idle slower than that.... probably half that speed.

[RM250crosser]

looks like it runs on water (sometimes)

[nickernosher]

leave it tick over as low as that for a tank or two of gas and you newly overhauled briggs will be prime for a nother overhaul

[Cantrell2500HD]

is this on itunes?

[BrundukasLT]

slow death?

[zigZag776]

This is nuts! Awesome engine though. I thought a few times it was gonna die out but it just kept on a chuggin.

[R5H4D0W]

what is that bending plexiglas sound coming from? and how do you kill the engine?

[ROCKNTV1]

they dont oil very well at that speed,,,not enough sling, cool sound though

[eshizz89]

i used to get my mini bike motors to idle like this, although they didnt sound like water bubbles.

[roro879]

Its because the rod is so worn,its got another 60 degrees of timing advance from when it was new

[guymark]

Amazing - love the little "bloops" and "pops" it makes too.

[gibbogle]

I used to have a Matchless 350 single that idled about that slow.

[klassetompa]

like mechanical heart.....

[KNGarver]

I want that on my car.

[outdoorsman310]

i got mine to go that low but now i readjusted the carb and it wont go that low

[lyerlyman]

I could actually hear it fire on the compression stroke at TDC. Awesome.

[nativebrother]

Love how it sounds bubbly, lmao.

[envelope91]

Oh man.. that sound is awesome

[kickass4510]

Your Website Dosent Work :(

[radicalnegative1]

@kickass4510 Sorry, I took it down. It was too hard to maintain.

[TheAjhomie]

haha nice stuff

[Sleeper260]

Hit vtec

[TR4351]

Thats what they put in Honda's, right?

[94cumminsdude]

nice but one thing i learned it dont get oil goin that slow

[MetalSkull420]

"INSANITY"

[SuperHoneycutt]

Owner:.paint this thing. Gives good service like that, it deserves a new paint job.

[Brodes1983]

Sounds like it should be blowing bubbles.



[deanschool]

another thing to determine is that this motor has no load on it, so i would generally rev up to amazing rpms if left alone so you can make this thing run on ALMOST nothing because the input shaft has no load for it to work the motor. thats when diesel pull trucks break shafts, the motor revs up to around 7000rpms and they have to shut it off.

[weldon0m]

sounds like my old harley

[seansweetaurus]

sounds cool haha

[duncan33984]

i like that sound!

[boilingpoint2]

very economic a this rpm

[pkrieter]

I love that sound !

[Jiggle582]

i have 1 more hp than you

[cfazekas0441]

cool

[stmotorsports]

you got one of them rare 8 stroke versions

[nonamejoe56]

good damn, I had a mower that could idle that slow, it was awesome

[ninjaneb]

made my cg idle slower ;)

[ImRichRu]

thats like 250-350rpm

not that slow

[Genners111]

I like the low idle plopping...

[Detroit8V92tta]

It sounds like me the morning after a hard night on the piss!!

[acidangelster]

Wow.....beautiful.Even though I dont know a damn thing bout these engines and the slow idle competetion (which i came to know of just five mins ago),its pretty awesome how you could get the engine to go as low as that.

[horsehaire]

actually not so insane, I have a Briggs 19D that idles at 250 rpm at complete idle

[horsehaire]

actualy not so insane, I have a Briggs 19D that idles at 250 rpm at complete idle

[wapperott]

CLUGA CLUGA CLUGA CLUGA CLUGA CLUGA ....CLUGA .SHFFFFFFFFFFFFFFFFFFFFFFFFFFF­FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF­FFFFFFFFFFFFF

[MrJohndeere55]

i have a kohler 15 hp and i can get it that low mayby lower and then it blows smoke rings

[LPFan3118]

Insanely cool!

[thedistortedguitar1]

It sounds like a hit and miss engine !

[Mrtechux]

woOOP bop bop WOOp bop bop bop WOOP woOP Dop dop hahahaha :DD

[SHAD0WZOMBIE]

cool, my tractor's 22 HP Kohler can get even lower though

[pyroman675]

your rihjt theres no way that that monster is only 2HP man, when i saw it i thought it would be like a seven

[fairyheli2]

i tried this but any slight disturbance to the engine and it cut out

[TheGazzers]

how do u get it to go that low on rpm's?

[radicalnegative1]

@TheGazzers A good, clean carburetor, great compression, and a heavy flywheel. That's really all you need (provided you have a satisfactory spark, of course).

[jack9102]

@radicalnegative1 it wont idle too slow if the ignition timing has been pre-adjusted for high rpm. because it is set too far in advance so it simply kicks back and stalls. your breakers must have been retarded (SLOWED DOWN) enough so it could idle like that. I have a 1990 7hp engine from a generator and it still has the armature on it, so it idles real slow.

[radicalnegative1]

@jack9102 I think the spark is automatically retarded about 20 degrees past TDC at starting and idling conditions.. I'll have to look that up in the manual to confirm.

[boaterbil]

@radicalnegative1 Doubt that with magneto and points. No TCI box to change timing when running

[doomsd46]

@jack9102 - That is why you get a Wisconsin. The gear driven magneto has a system, that at low speed (10rpm-ish) will give a strong spark. I have actually turned it by hand as slow as possible, just to the point when it should fire, then tapping in gently until it clicks, and you will feel it fire, but not enough to get around to another cycle. Makes them wicked easy to start though!

[radicalnegative1]

@doomsd46 Search for "Starting the beast by hand." I have a video of starting my Wisconsin doing just as you described. You can't beast a Wisconsin engine. It's just not possible.

[h2lkid]

@radicalnegative1 are you sure the oil slinger is working at that low rpm?

[h2lkid]

@radicalnegative1 are you sure that the oil slinger will work at that low rpm?

[radicalnegative1]

@h2lkid I assume that it does not work, which is why I did a little "extra" lubrication at the beginning of the video by running it at full throttle before running it so slow. Running engines this slow for long periods of time is a great way to damage your engine's internals.

[h2lkid]

@radicalnegative1 yeah

[JakeWeb93]

@TheGazzers RPM not rpms. its per minute not per minutes, lol :)

[Newgrounder02]

sounds like its fart'n bubbles lol

[robviolin1]

great vid. Glad you mad this vid. Thanks

[flyguyviky]

That thing is to big to be a 2 hp

[highperformace86]

i can get my 12 kolar engine that low

[radicalnegative1]

@highperformace86 Is it a K series Kohler? I have a few of those on my Gravelys that will get down to about this level.

[highperformace86]

@radicalnegative1 12hp magnum best engine kohler made

[outdoorsman310]

@highperformace86 same

[KapteinOpel]

How did you get a 2hp shroud to fit a 5 hp engine? As I remember, they are different sized also physically on the outside?

[radicalnegative1]

@KapteinOpel The shroud is original. The 2 hp you see is a decal that the previous owner put on.

[schindlerman96]

what is the motor off of it looks like its from a tiller

[radicalnegative1]

@schindlerman96 I don't know what this engine came off of, but you're right about model 14 Briggs, as they were indeed very popular on tillers.

[schindlerman96]

@radicalnegative1 well the motor just looked very similar to one my dad had on his old craftsman tiller

[specialks1953]

You won't find an engine today that will idel down like that. I remember those old engines. If it was adjusted correct it will idel down low and run just fine at normal speeds.

[funtarded]

It sounds like Flubber!!! Probably a combination of oilbath air filter and low revs leading to this. Cool vid! Keep it up.

[formerkillerz]

the reason i can idle so slow is because of the automatic compression relief for starting or when its cold thats what makes it sound kinda like its under water

[therealcato]

Might wanna get a longer Exaust system cause a short one such as that pipe sucks in cold air and can warp a vavle

[RainJetSprinklers]

I've gotten one to idle almost that slow a couple times before. Briggs engines were great before they went to that crappy slant OHV design and now I wouldn't touch one.

[Deereboy011]

if i did that my mower would stall 3 seconds later

[mowerwizerd]

old engines like this are build alot! better than new one's

[killerdeamonking]

Ok i will tell you all why this engine can idle that low its super simple the fly wheel is heavy enough to complete the cycle there for firing at a slower rate there's no way to prove me wrong as i work in a small engines shop at my school ok ill put you up to a challenge try that with a newer engine it will fail big time due to the aluminum flywheel.

[highdeserthater]

i got my 5 hp OHV on a mower down to like 350-450 rpm. i dont really know. but it fired 2 times a second (22 times in 10 seconds) so you do the math ya know? lol i dont have that engine anymore because i gave it to the family who bought our house

[SeberHusky]

BLOOP BLOOP BLOOP BLURP BLOOP BLURP BLOOP

[Hallaran]

That has got to be some kind of record!

[cripso123]

That's idling so slow you can hear when the plug fires!

[docstruthers]

HILARIOUS. I have a opposed twin B&S and had it idling pretty low once. They are GREAT motors.

[abeemanator]

if you put two stroke gas in it you could run it like that without worring about it burning up the rings.

[theMadUkrainian]

Have one of those from a early 70's rider. Powers my log splitter like a champ.

[zildjan5b]

them motors are good motors i have one the old simplicity wonder boy i have and i can get it to idle pretty slow

[mowerwizerd]

i might be wrong but i think that that engine is lacking compression?

[radicalnegative1]

@mowerwizerd Its compression is actually very good because of he new rings.

[Imprezaman555]

@radicalnegative1 It must have a low compression ratio then, otherwise the engine would slow down too much on the compression stroke.

[radicalnegative1]

@Imprezaman555 From strictly the engine's bore and stroke, its compression ratio is 6.89:1. However, that does not include dead volume when it's at TDC. I do not have that figure.

[MrShawn305]

@radicalnegative1 Side valve engines like this one are naturally lower compression than ohv engines because of the increased volume in the head. I'm not sure what this model would be though.

[gonitronow]

@Imprezaman555 A probable reason could be that the old engines have heavier flywheels and more mass=more momentum=lower stall speed(in this case)
