I believe I know what your problem is. I've seen this before. What you replaced was the fuel pump, not an oil pump. That is not your problem. The line running from the engine crankcase to the fuel pump should only be supplying air pressure to turn the pump internally. If you have oil in that...

Could be an intake push rod as well. It may not be firing because no fuel is getting into the cylinder. You need to remove the rocker (valve) covers.

1) I agree that it's probably not a fuel/carb problem, but make sure the choke is open to make sure enough choke cleaner/starter fluid is getting through the carb. 2) How are you checking for spark? I wouldn't just trust a spark checker. From my experience, the problem is rarely the spark...

RA8HC definitely works. I use them to replace 14 132 11-S1 about 20 times per year for my customers. Never had a problem. I always have them in my inventory.

Thank you for the replies. Here's an update: I did the leak down test. This was my first time doing that. The pressure pushed the piston down. It was do longer at TDC and the exhaust valve was open. Is that normal? I had to use a wrench on the flywheel nut to hold it at TDC. At that point, the...

I'm working on a B&S two cylinder engine 44K777-0125-G on an Exmark zero-turn. The exhaust valve seat came out of one of the heads. The valve got stuck open. That allowed the push rod to pop out of position. It ended up twisted and mangled inside the engine which also destroyed the camshaft. I...

I think you're barking up the wrong tree. If the engine was cranking and just popping and backfiring when you sprayed carb cleaner into the air intake, that sounds like a valve problem. You might have a bent push rod or valve lashing way out of wack. Take the rocker cover(s) off and see what's...

Did you figure it out? If not, are you sure you aren't getting power to the starter? Maybe it just seems like the starter isn't doing anything because the engine won't spin for one reason or another. I've seen this happen for different reasons: a seized PTO, compression release failure and from...

Thank you. That's all good information. I've never messed with boring out a lawnmower engine. I won't be doing this repair if that's required. I'll check for more damage.

Ok, I have one more question. Do you think I should replace the piston rings since I have to remove the piston anyway? Ok. I'll give it another look.

Thank you for your reply, Fish. You have a good point.

Ok. That's a good idea. Thank you.

Thank you for the replies. Bertsmobile1, have you repaired an engine with this kind of damage before?

This sounds like a blown head gasket on the low compression side to me. Pull the head off.
