My Kohler has the same symptoms, was getting ready to buy a new mower, now I’ll try the head gasket. Great video, thanks!

@MowerMike 2 года назад

Good luck, check that the oil level isn’t high first. A lot pump smoke just because they have been over filled with oil.

@mikelute77 2 года назад

Thanks for the video brother! I’m tackling this on my father in law’s mower today. Much appreciate your in depth video sir

i HAD A FIRE at the same cylinder. No idea what caused the fire. replaced a bunch of parts that burned,breather and hose magnetos air cleaner and such. after that it ran great but started blowing smoke from that side of the engine. thought it was from the breather not right until now it quit and wont run. looked here and saw the possible cause was head gasket. now your video showing the fire the same as mine but i was further away from my extinguisher so it did a lot of damage. thank you for showing that a blown head gasket can start a fire. working to change the gasket now. thanks again.

Wow, ya fire on an engine is always scary. But hey if you can fix it will be a cool fix and you have a cool story. Good luck on the head gasket just take your time step by step.

Did you reuse your cylinder head flange bolts or is it necessary to buy new ones for proper torque?

@MowerMike 2 года назад

Ya you should be fine re using the bolts. Atleast in my experience

@limogesfarmer6326 Год назад

Great video: just not clear on the using a screwdriver to find TDC: That part sounds critical. I would assume a work-around is to rotate the flywheel until you see the piston is in TDC, and then mount the cylinder cover and valve assembly.

@WillliamLuch-ul2lh Год назад

I'm not sure how to determine what is Top dead center on the compression stroke. How can I tell when I'm on the compression strike? Thank you.

@MowerMike Год назад

When both valves are shut you are on the compression stroke. They are shut when the pushrods are down and not pushing on the rocker arms. If one one is pushing on the top of a valve then go another rotation until both rocker arms are loose. Good luck

Nah I never had any issue with those pads. Just make sure to clean up any dust they leave. Check out this video for cleaning the head ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IP4JtREZP3A.htmlsi=leAqyMLoZdWHoru8

@garywilley8118 Год назад

Thanks, I'm going to be replacing the head gaskets on my sv725 and it really helps to see how it's done and, the little tips on how it can be done a bit easier, prior to doing the job. Lol The only thing I thought I might do differently would be to remove the cylinder shields, cover the carb. intake and THEN pressure wash. That way the engine would be clean and all fasteners etc. would be easier to see. Is there any reason you can think of I shouldn't do it prior to doing the repair?

@MowerMike Год назад

Nope sounds like a good idea, just make sure the plugs are in and the intake is on so you don’t get water in the engine. Good luck

Ya, it fills the muffler with oil, and leaks everywhere, all it takes to catch fire is a backfire when you shut it off, mine backfired, and caught fire.

Hi Mike. I just took the head apart on a Kohler Courage lawn mower engine. There are no rocker arms. There are no guides for the push rods. The mower ran, but blew white smoke. Is this possible? Or am I looking at a different engine configuration? Thanks. At least your video got me brave enough to give it a try!

@MowerMike Год назад

Hmmm never seen that engine. I will tell ya if you replace the head gasket and it is still blowing smoke you may have worn out piston rings. Good luck

@wendaworkman8065 11 месяцев назад

Mike tha ks for responding. Yes. It had rocker arms. I've got the whole thing put back together. New carburator. Fresh gas. Oil changed. New filter. New gas filter. Gas line open. Mower will crank. Won't start. Any thoughts? That do t involve shot guns?

@matthewmckinney1326 2 месяца назад

Would gas in the oil be an indicator or bad head gasket?
