Briggs and Stratton Problem

[Hond400ex]

the float might be stuck

[pcblah]

i saw his vid of taking apart that engine... it was the magnitos rubbing on the fly wheel :P

[emperor525]

check that the primer gasket is sealing to the face of the carby. Or the carby bowl gasket (O-ring) is not sealing correctly. This will not prime the bowl and allow the main jet to flood the venturi.

Cheers.

If you guys need help just let us know AYE!

[pierce4484]

pull the head and check for blown gasket between cylinder and push rod cavity if it is ohv (over head valve). i see a lot of these blow in this area and it will suck oil from this point. i work in a small engine repair shop.

[BATMEX44]

@pierce4484 you right, thats why is burning oil..

[piroromero1]

seems to me that the valves are not opening properly, remove head and see. may have heavy carbon built up.

[mark16443]

Gaskets maybe, watch a vid on how to dissasemble it and look it over and look for any cracks bad gaskets ext

[bowietruck2000]

when i am cutting and i hit a thick spot of grass the mower boggs so i have to back it up so the mower speed up, i try everything that i know of,can you tell me more. bowietruck2000@yahoo.com

[MrTheGrimOne]

drain the gas $20 sez theres water in it 

[Sextioneight]

That's a SIMPLE FIX !... Your main jet is clogged . <Notice the period ?

[motorboy171]

why do you prime so many times?

[sciencekid17]

your engine has water in the carb... empti it out and it will stop stalling

[jakedually]

take the carb off and clean it.theres dirt in the pick up

[mike02207]

i would check the piston rings and replace them and have your local briggs and Stratton dealer check it over be cause the are the are under warrenty supposed to start in two pulls or less

[todking]

It is over full on oil, makes compression high to start and will smoke badly

[SCHensley]

I had a 5 hp B&S that ran great, when it started smoking like that, the rings went shortly after. Seems there may be a ring problem.

[randall2051]

@SCHensley no its a fuel problem, also a compression check will prove you wrong

[ElijahWheeler]

prolly sat on its side.

[TheSnowmobileman]

sounds like it has low compression when the piston rings are bad it smokes like crazy and it would not like to start check your compression

[busterhound333333]

you do know that you really shouldn't grind on a starter of any kind for that long without stoping and giving it time to cool down ...right?

[grabba73]

bike rims, what the hell is that thing????/

[semco72057]

It sound like it is having problems getting gas. I would check with the DR company to see what they say about this problem.

[fred30680]

It started so you know its getting fire.

You keep pumping the primer to get it started that ought to tell you its starving for gas. Check to see if it has gas in the tank. Check for a gas shut off, Then the gas filter , Check the gas linkage, Clean the carb bowl. Clean the carb.

[Steelaworkn]

It's not getting gas. Clean the jets on the carb and you should be good.

[3211chris]

I agree with VintageClassic1 over full of oil and a dirty air filter. even if the rings were worn out it would not blow oil all over the floor. drian the oil and clean the crank case breather fill with oil (dont over fill) check the air filter its prolly full of oil. and it will run like a new engine as it is a new engine.

[partyboyperk]

i think your float is sticking closed my 6 horse briggs did the same thing

[magicthekitten]

like the man said store it on the level, my lawnmower does EXACTLY the safe if stored at an angle. Rings are fine its just burning off exess oil thats got into the cylender.

Also make sure you arent over filling with oil.

[ALEX62592]

could be the intake value isn't timed right or the excust value

[fdick9]

coooooooooooool dude smoke

[andy26111]

its not the rings if it was it would be puffing out blue smoke it might be the diaphram in the carb might be kinked

[ad356]

the larger briggs engines DO not have a diaphram, only the little 3-4 hp "classic" engines do. this engine most likely has a float carburator. maybe the float is getting hung up?

[partyboyperk]

@andy26111 those carbs dont have diaphrams

[the5445]

clean the carb before you do anything else

[bryan7771]

i think your piston rings are bad

[19wael96]

the throttle is not responsive

its like just choking the engine

[dw807]

Put a new spark plug in it. Change your air filter. Store it with a wood block under the blade, I noticed the way it was sitting the cylinder head points downward which lets all the oil run into the cylinder which makes it hard to crank and produces lots of pretty blue smoke. The oil can also ruin the spark plug.

[gokartfreaker]

lots of smoke...

i think the piston rings are shot

best solution:complete teardown and replacing of the rings.

also check the settings on the carb and clean it out!

[Nolimits80]

It was running too rich, it wasn't burning oil. If the

smoke is blue then it's burning oil

[kc5jdg]

Could be the rings. have done a leak down compression test?

also check the breather tube that goes from the valve spring cover to the carburetor. If it has a lot of oil in it, likely your breather cover is at fault. I'm sure you are fouling a lot of spark plugs. Don't clean them, just replace them. but figure out if the oil is coming from the valve cover first. There is a wafer valve in the cover, and it may not be sealing properly.A broken or severly worn oil ring may be also it.

[theduderene]

did you put in pure gasoline or mixed with oil?

[frenzieddrifter2]

i think you have a problem with your piston rings

[frenzieddrifter2]

dude, i'm only 12 years old but, I think theres a problem with your piston rings and maybe you should also time the engine cuz it sounds bad and doesn't idle

[zerofactor17]

and im alsp sorry for saying what i did you know dude briggs dont suck but maybe you do with working on them im sorry please dont hate me i didnt know that you work on engines like me

[floydturbo2]

Looks like too much oil in it..

[zerofactor17]

yeah i have worked on small engines since i was 7

[zerofactor17]

there is to much oil in it take all the oil out and then go to who ever website from who you bought it from and find the specs on it and find out how much oil to put in it. I have had the same problem before and i did exactly what i told you to do and it worked. please get back to me if it worked thank you

[robby844]

wow i got the same type of engine on my craftsman mower of the same POS and it has a dipstick so you cant go wrong with the oil.i say junk it its a briggs

[zerofactor17]

dude briggs dont suck maybe you do with working on them

[robby844]

wow ok i got more years working on them then you do i rebuilt my first 5 horse when i was 5.now im working a single 16 hp synchro balance.and yes the new briggs suck dick.

[zerofactor17]

cool im working on a tecumseh 3.5 hp horizontal shaft that i bought off of ebay that after i got it it seized before i could get to working on it

[Briggsmaster]

i like the older briggs better

[carbpumper]

briggs and strattons are just as good as hondas and have been around a lot longer.

[robby844]

when have they EVER been better?

[anbd1993]

ok i have the same problem. i solve it by changing the carburatorwhen the engine stop your carburator keep air and when you start it it pump fuel just for awhile you have 2 options to fix it you change the carburator or you take a piece of metal and you put it front of the carburator so it will pump fuel because it cant pump air easy and it will pump the air which is stack in itkeep going

[robby844]

WHAT?

[whitmer1993]

it is ur valve's

[76hotrodF250]

Also, another thing to consider, though highly not as likely, but still could happen, is that when the cylinder has honed, it could have been honed out wrong, ethier off a little, as in instead of being perfectly true in diameter, it could be a little oblong or oval just enoung to where it is not a true circle cylinder hole, that can throw all kinds of crap off from being able to run right, also possible is that the cylinder diameter is not the right size.

continued....

[76hotrodF250]

from last post....

Something you should think about, these engines, and all other small engines, are thrown together on a assembly line for mass retail production, the manufacturer goes to great lenghts to try and produce quality motors in mass droves to make the customers happy, but defects are still abound to ocure, its something that is unavoidable, face it, its reality. This motor of his is one of many lemons that happen in the industry of small engines.

[76hotrodF250]

Your Welcome! And yes, you can apply this to all engines, I have over 10 years experiance working on engines, for lawn mowers to huge diesels the size of a 4 door car!!! If he where to completey take it apart, he will find the cause, which I noticed he has in another vid.

[76hotrodF250]

The motor is trash!! OK, its not the carb, its the rings causing that, sometimes the rings get put in wrong causing this, I have seen it a lot, also the rings have a gap between them, when they are put in a motor, the rings gaps are NOT supposed to line up, if the ring gaps line up it will also cause this. That screeching you are hearing is the rings scraping the cylinder wall, its destroying the motor everythime you start it up. These things happen from time to time, you bought a lemon!!!

[76hotrodF250]

Etheir way, this is a bad motor to start with, its just a bad build, I have seen it before like this right out of the box, hard starting, screeching scraping sounds, its all in a bad build up from the factory. Could be the a ring was put in upside down, I done that once before and ruined a 5hp briggs in 5 seconds, I was younger and didn't know what I was doing, I put in a new piston and rings and screwed an otherwise good 5hp briggs all to crap.

What keeps the rings from aligning is cont....

[76hotrodF250]

from last post... is when the rings are installed, and you put it into the ring compressor to install it in the cylinder is pure tension, the rings are under tension and once in place in the cylinder, they generally down move around from that spot, now it can and does happen from time to time, also if the wrong size rings are used it will cause problems, like scraping of the cylinder walls if it big of a ring, or oil blow by and smoking if the rings are too small. Just some things to think about

[johndeeremig]

get a carb rebuild kit it sounds fine i have one good just clea decide what to do, I would replace all the rings or make sure the rings are not in split area ligned up 1/4 from 1st ring to the last ring

[GODZILLAMANASS]

ROFL!!! So you are saying that oil spitting out of the exhaust is caused by a faulty carb ROFLx2

[krankiev]

carb gasket

[kpj200]

Are you kidding me? Obviously it's the compression rings are installed wrong!

[krankiev]

i didn't read the description of thew video

[kpj200]

It's not stated in the description, It's just common sense for a Gear Head!

[krankiev]

i haven't ever experienced one like that yet

[kpj200]

I used to fix small engines and it's very common in the shitty B&S's!

[krankiev]

briggs is not shitty this is just a bad one

[kpj200]

B&S has the most call-backs for small engines right now! and you're telling me this is just one bad one! Look on YouTube and see how many videos are about B&S problems!

-KPJ200

[krankiev]

also take into consideration that B&S makes up a very large portion of the small engine world- probably the largest. This means that they could be the same or even better quality than competitors but still have more callbacks...

[kpj200]

Not amount! I'm looking at percentage! Honda makes a higher quality, longer-lasting engine for a little more buck! I don't like their cars much to none but I adore the Honda motors. Even the Honda Clones outlast most B&S's!

[krankiev]

well you should have explained it better...

agreed, honda cars suck but they do make some decent engines. Except the Kei-Hin carburetors they use are absolute rubbish.

[kpj200]

There are little to no videos of Honda problems! Then type Briggs and Stratton problems and see how many results in the search criteria pop up!

[krankiev]

will you just shut up i never said anything about honda problem videos

[gokartbuyer]

@kpj200 no they don't i had a honda 5.5 for 2 years and it was well maintained and it gave me soo much shit!!! i bought a briggs 6.5 flat-head and it saves more gas ,hauls more ass,and cuts a whole lotta grass! it starts first pull every time.

[30GB]

it might need new rings or too much oil coming out of the breather

[roxasraid]

it sounds like you need to tune your high speed needle

[Treddtruck]

my briggs and stratton starts great.I am not against them.

[DanielJaegerFilms]

I've been working on it, and I've now got it starting on the first pull! I think I'm gonna change the name of the video to something less critical of Briggs, because what really got me upset and made me put up this video was because Country Home Products claimed it had a 2 year warranty. However, because it was purchased on a buisness account, they only gave me a 90 day warranty! And by the time this thing started acting up at about 15 hours, the warranty was over! Thanks for the comment.

[DanielJaegerFilms]

Oh, and I've got another video of it starting on the first pull coming soon. Just a little work and it runs like new!

[pcblah]

@DanielJaegerFilms help me i hav a briggs 3.5 hp and it wont start D: it was running yesterday though

[jeffwins24]

@pcblah clean you carb it most likely clogged

[pcblah]

@jeffwins24 it was flooded... took out the spark plug gave it a few pulls then put it back in made it start :D. now the govenor spring is taking a shit on me... oh well got a new 6.5 for my gokart

[wind4watts]

I strongly suspect that the carburation is way out, it starts on choke after you flood carb, i would think your 'running'mixture screw is way too far in, giving over lean mixture take it out 1/2 turn and count them as you go. Makes them a pig to start. I had exactly the same problem on a brand new WOLF 950 generator, would start then cut out as no fuel. Could be something else like debris in float chamber, hard to say without being next to it.

[DanielJaegerFilms]

I've never adjusted the mixture screws, but that's a good idea, I haven't thought of that yet. I'll give it a try.

[wind4watts]

My generator was brand new and hadn't been set up/tested at all, often they only have a single mixture setting to cover whole rev range so u usually have to have it a little rich, when it runs sound ok for an enclosed space, a a bit of muck at btm jet hole can cause it also good luck!.

[DanielJaegerFilms]

I'm gonna take it apart today and work on it. I'll have videos of the process. Thanks!

[fordwillkillyou]

well.. you cant blame the engine.. all my briggs have been nice to me. yours must have been born with a deise or something... it shouldent run like crap brand new.. but i can understand your frustration towards it lol

[DanielJaegerFilms]

Yeah, I'm coming to a conclusion that it must have been defective or something, becuase I've got friends who have the same engine, and it works perfectly.

[lovemyrv]

ha thats the first Briggs & Stratton i ever seen too be a bitch like that too start, must be the lemon of the series.

[DanielJaegerFilms]

The more I think about it, the more I think it must be a lemon. I've heard people say bad things about Briggs and I've heard people say good things about Briggs.

[VintageClassic1]

Only reason It runs like that is becouse it needs maintenence. I doubt the rings are bad. Not with a 50 hour engine. If it smokes it's likely to be the crank case breather that is clogged. The rough running is carburation. Dirty carburator/improperly adjusted carb. Carb needs rebuilt. You do that and you'll have an engine that will fire at the slight hit of a key if you know what to do. 90 percent of MY work is carburation. It's not fault of Briggs it's self. It's poor maintenence.

[CCDProductions]

take the float bowl nut off and clean out the little holes. then spray it out with your compresor. make sure you didn't overfill on oil.

[1944johndeerel]

you just cant use the lower end briggs the high quality ones work better and last longer like my 26 briggs fh which has a funky govenor but still starts and runs good. it hasnt run in a few months so ill make anew vid soon of a real briggs cold start

[DanielJaegerFilms]

Yeah, I've heard a lot of bad about the INTEK type engines, but I've also heard the VANGUARD type is good.

[hotrodkid7]

its probabily just a lemon from the factory. i own a farm and I have 1 26 hp briggs and stratton on my 54' cutting lawn mower. i actually like the briggs the best. then i have a 25 hp kohler on my 50' cub cadet, a 5.5hp honda on my push mower out there. and a tecumseh on my snow thrower. i like the kohler the least to be honest. i mean no major problems, but it starts hard, and when it does start it blowes out a huge cloud of black smoke that stinks my barn up.

[1944johndeerel]

you have a hard starting kohler you should see my 1977 john deere 210 it has a very fast starting kohler k241

[suchfunstuff]

Cracked ring. I see that smoke coming out when it quits, then after starting it. Must be fouling the plug with oil, causing ignition failure.

[DanielJaegerFilms]

But why would the piston ring fail so early? It's only got about 50 hours on it.

[suchfunstuff]

I have seen stranger things happen. Check the breather, make sure it isn't broken. If it is broken, the crankcase isn't venting properly. I have seen defective breathers cause engines to run poorly.

[DanielJaegerFilms]

I kinda new, but interested. What is the breather? The air filter or something? And what exactly do you mean by the crankcase venting? Thanks for your help, guys! -Daniel

[suchfunstuff]

The breather is in the side of the engine block. It is there to open and close, to ventilate the crankcase pressure as the piston goes up and down.

[DanielJaegerFilms]

I'm gonna take the engine apart one of these days, I'll let you know how it goes!

[tordeg]

Thats is the strange part... mine was running ok form the day i bought it.. But i hav a frind with the same engine and it has been in and ont from service....

[tordeg]

Have the same up here in Norway, but i have never had a problem with mine..... strange....

[DanielJaegerFilms]

What do you think is wrong with the engine? I think it was just a lemon from the start.
