Kohler fills crankcase with fuel

What gives? Sears craftsman 917.275180 with a Kohler courage 19hp SV590S 0004 3515100863. Fuel drains from fuel tank through the carb and fills the crankcase. Cleaned the carb. Replaced the fuel needle and the solenoid. the float is non-ajustable, but it seemed like it was correctly seating the needle. the needle does not stick. New fuel, oil, and air filters installed too. fresh oil and it runs great. hope I didn't miss any info. How do I get it to stop leaing the fuel in to the crank case?

Could be your float is not floating to close the needle valve. Shake the float and see if it sloshes.

It didn't have any fuel in it when I had the carb apart. I will check it again. i never encountered fuel inside a plastic float. Have had brass floats with fuel in them. Anything is possible.

Take a Qtip and clean the seat area well.

Cheese you are right, Again. I pulled the carb again. used a q-tip and pulled a ring of crap out of the needle seat. So, I must asked, is this an issue with the fuel quality, or the alcohol content of the fuel? Is it eating the rubber tip of the needle? Thank you for your help. I will make sure that I "q-tip" ever one I ever work on in the future.

If you are using "E-10" that could be the problem. E-10 is raising hell with everything. Ethanol is not good. It attracts water. Also the quality of today's gas sucks with all the EPA mandated addivtives they use.
I suggest using "SeaFoam" in the gas for at least the last 2 tanks of the season and in the last tank use Stabil and also use isopropel dry gas.

I guess it's the quality of fuel nowadays... seems like carb problems are more and more common. I also think it's partly due to the quality of materials used in the carbs and fuel tanks.

I have been told by a few people that ALL gasoline today has about 10% ethonal. Maybe this is just a local thing, i don't know. but it would explain some of the carb issues I have seen. Green algae gue, yuck!! thanks again.
