Same, found the valve in the cylinder.

Don’t need it , use hose screw clamp

Yeah what a cheap way to make a buck. Force average maintenance to require a whole breakdown. My 2000 Honda Xr100 is easier to work on than this.

Mine is the same way and i was wondering if it was up or if thats how it was supposed to be. The intake looks like part of the block but tbe exhaust seems to have a retaining ring on it and i noticed it is higher up like his. Wasnt sure if its supposed yo be like that or not the spring and around it is also cover in hard black burnt oil or somthing so im wondering if that is the problem ? Thats why im watching this video trying to see if anyone else has this build uo problem and why it is happening?

Working on a neighbor's unit now. The valve guide protruded out until it stopped the rocker arm and broke it. Going to try the high temp Loctite fix on the valve guide and hope for the best. How did you address the issue with yours?

marks on the flywheel are from the brake

Yes. It started right up. But I realized after assembling that I didn’t install my new timing belt & used the old one. So I have to disassemble again.

Tom,at least second time around will be easier.Good video.

I was thinking that was way too much. I do .006 and .008

Exactly!

Exactly. I don't know what the hell he is talking about!

@@jackwilliam2226 The manual lists the gap in mm, do the conversion if you need to.

Yep the belt is covered in oil

I used tooth paste to seat the valve if I remember correctly.

Toothpaste????

Did you ever get a fix figured out. Working on one for my neighbor now with the exhaust valve guide pushed out. I believe I am going to try high temp Loctite, but I was curious if you had a better plan. I am doing it as favor, so I am not splitting the case. If it goes that far, I am telling him to junk it.

@@ericpigg2689 same issue with mine broke exhaust rocker and adjustment nut fell into engine so had to disassemble entire engine, used green loctite worked for about three cuts the guide came back out and broke cam again im gonna try a intake valve seat in and see if that works this time . Locking at his engine his guide is sticking out and gonna be A issue soon

Hey Barry, been looking a a few posts. Could be a few things. Look at post: www.google.com/amp/s/www.lawnmowerforum.com/threads/help-briggs-stratton-popping-or-backfiring-through-the-carburetor.5204/%3famp=1

@@tomlang7692 thanks i will look but it has no compression

Yes sounds like leaking past the valve seal. I think Autozone lends crankshaft puller if u are disassembling.

He used MM not standard

nope

@@shannonsizemore438 well I hope I never have any problems with the valves sticking on mine, I hear that's a common problem

I honestly this engine seems to be very simple and easy to work on you should not be intimidated by this job. Id say most complicated part about this engine is the carburetor lines and the only reason i say that is because mine has alot of gas lines and i can see their dry rotted so if i need to clean the carb i already know im gonna spit every line and have to buy new ones. Really cool little engine bought mine for 10$ at the worlds longest yardsale was on a broken pressure washer slapped it on my go kart and loving it. Does seem to over heat quickly but i think i have some type of exhaust valve problem too but still runs like a champ until it gets hot then it starts to blow smoke until i let it cool down before continuing to thrash it.

Yea, most people just buy new mower. It is great experience if you have the knowledge & can R&R valve. I have auto degree so I kinda challenged myself to see if I could do it. Assembling the 10 separate video clips was another challenge.

Thanks Russell. Oh yeah I reassembled and forgot to put a new timing belt on and I think that’s where I ran into problems so I have to take it apart and redo it again.
