So after bringing my PT-425 (Kohler Command Pro 25) home and changing the engine oil (synthetic - 2 quarts), the fuel filter, the hydraulic filter, cleaning the air filter, as well as greasing all the zerks, I began using the PT to move some heavy stuff around the yard. I ran her for about 2 hours on and off with no problems - until I went to temporarily park it. I moved the throttle down to idle and it shut down instead of idle. Wouldn't start again. Smoke out of the exhaust when cranking. I immediately checked the engine oil, which showed me it was a bit over filled (it was just a hair above the full line when I changed it, even higher on the dipstick after running.) I checked the spark plugs - they are black, but not wet. I checked for spark - it's there. I checked if she was getting fuel by disconnecting the fuel line at the carb, and after a few cranks - fuel shot out. I tried starting fluid, nothing.
I cranked it with both plugs out, and I can feel compression with my thumb over the plug hole on both, though the passenger side had a touch of oil on my thumb. Nothing sounded bad when I was running her, the only other thing I noticed is the carb is wet when I look down inside. Could it be that I put synthetic in it after 650 hours of running I don't know what in there? Could I have overfilled it and broke something?
So my first day really using the PT has been frustrating. I drained some oil so it's reading in the middle of the dipstick fill level, and I'm gonna get new plugs tonight. Other than that, I have no clue what to do. Any ideas?
