Hello all! I have a kohler command 18hp that will turn over but not start. It has fuel, fire and air. Odd thing is when I remove one plug the engine will fire and run. I'm thinking clogged exhaust???

:wave:

That is odd. I would think it would be more apt to run with the plug in the one cylinder vs it being out.

shorted plug,
exhaust valve not opening.

plugged muffler, it would start, but die after a minute.
