Need help with why my Kohler has lots of gasoline in the oil, also the drain plug is frozen, I want to remove it maybe with a breaker bar?  By the way it runs with the gas in the crankcase.   Bianco

Welcome to the Forum :wave:

Having gas get into the crank case is most likely caused by your carburetor needle valve not shutting properly and allowing it to overflow.

I would not recommend running the machine until you get this issue resolved as the oil gets thinned out by the gas and will eventually lead to major problems internally.

 

What model engine is this?

Lots of knowledgeable guys here that should be able to get you on track.

Thanks, that sounds cheaper than rings or a disassembly.  Not sure of model, I have to clean the tag, but did that once and all the print came off too.   Bianco  (on a different engine)

If you have a mechanical fuel pump below carb, Probly do, sometimes the diaghragm in those can get hole in them, and gas flowing thru it also leaks into case then, thinning oil. Harder to find pumps now and some places have kits, but not many.

Should be a Kohler Magnum 16 twin cylinder.

Change the oil before you run it again, you can mess that engine up fast running it with thinned out oil.

Just checked my Kohler 16hp twin cyl.   Started right up,  Looks like the pump is beside the carb.   I'm going to remove/rebuild.

A good backup to this issue be would be an in line fuel shut off. A lot of the cub cadets had the tank above the carb and thy will leak down.

There is a guy selling a much better replacement fuel pump for these right now on Ebay. It is an ACDelco, he has a bunch, $49.99 which is cheaper than some of the used fuel pumps I've seen for sale. I just put one on mine. It is an all metal pump.
