kholer no fire

Has fire getting fuel on one cyllinder next thing could it be a bad intake manifold? Bad air leak. Or are the vlaves working?

I've sprayed carb cleaner all around intake manifold while running and no changes in ram. valves are working and are set at .005 at top dead center. can a warped head cause this problem? I checked it when I replaced the head gasket with a straight edge and it looked good, and I now have 150 lbs of compression.

Valves adjusted at TDC on the compression stroke?

It sounds like you're dealing with a tricky issue on your Cub Cadet mower. Since both cylinders have spark and you've set the valve clearance correctly, there are a few things to check. First, inspect the carburetor and fuel delivery to the cylinder with 125 lbs of compression; it may not be getting enough fuel. A clogged jet or fuel line could be the culprit. Additionally, check for any air leaks in the intake manifold or gaskets that could affect the air-fuel mixture. If everything looks good there, consider testing the compression again to ensure it hasn’t changed, and double-check the timing as well.

I undo the valve rockers on the dead cylinder and apply shop air pressure to the cylinder. There will be some air escaping out of the crankcase, but not past the intake or exhaust valve. This engine should run even with the difference in compression on that side, but I have had a leaky valve trick me before on these,

Has the flywheel key been checked to make sure it is not partially sheared?
