Smoking Gun { well Kohler OHV }

I have a Kohler command 13 OHV mod #cv13s ser #2601716512
Have had for about 60 days it has been working great until last night i hit a hole in my yard the mower shut down and would not restart
i waited until today to try restarting it .. it fired up but is blowing blue smoke and excess oil on to the right tire
what could be my problem ?
just a note when i first got the mower the carb needle was sticking and leaking gas .. it would shut down the eng it would restart ... but have a hard restart
i removed it and cleaned everything and it has worked great until now ???

Welcome to the forums.

If it's blowing blue smoke then it's burning oil.

First thing..... check for gas in the oil. If the oil was thinned by gas then it will get by the rings and you'll be burning oil. Your carb. may have flooded and ran into the cylinder and down into the oil sump.

As mentioned, if it's blue it's oil. I would also check the crankcase breather line. They're not the easiest to get to sometimes, but they're rubber, and subject to a lot of heat, so can get pretty fragile. Once you locate it, you should be able to see whether or not it may be the problem, without having to actually pull it out. The heat of the engine is enough to cause sloshed oil to smoke, so would appear to be burning, but, again, you'll have to watch it and see if the smoke is coming from the muffler or maybe elsewhere.

Hitting the hole could have caused the oil to slosh hard and enter the combustion chamber. It usually takes a pretty dramatic stop and tilt motion in conjunction with an overwhelming load that stalls the engine for this to happen. This makes it hard to start and the smoke when it does. If it clear right up, the oil level is fine, and the oil doesn't smell like gas, everything is probably okay. If not, the carb may still be leaking gas into the oil.
