Hi, I have a exmark 60" with a kolar 25 command. Its sucking oil through the intake. Compression is good, I was told to check the dip stick and it had some play so I put silicone around it and sealed it. Is there a pvc valve or something on it? Help?
I have a yazoo with a kohler command 25 hp and had a similar problem. The fuel pump was cracked and it was allowing oil to go into the carb right through the fuel line. I thought it was ruined but after replacing the fuel pump the problem ended.
