Kohler Engine problem
I have a Sears tractor with a CV22S Kohler motor. It starts and runs well, lots of power. The oil level is good. It does not burn blue smoke from burning oil. The compression in both cylinders is 75 lbs.
The problem is....when the motor is revved up...oil is discharged from the vent in the fuel pump. The oil is obviously coming from the vaccuum line....but why?
I have owned this tractor since new in 1997.
Does the fuel pump need to be overhauled? ...any info would be 'preciated
