Hello, I had a problem running my 150 today. It would not idle well and did not have enough power to get on plain. I removed the cover to find oil everywhere. The cap on the upper oil tank had split like they all do. While i had the cover off I also checked to plugs to find they were very oily. I replaced the cap and cleaned the plugs. I put in again only to find that it still ran bad and was still leaking from the new cap but from under the threads now. I removed the plugs again and they were fouled again. Could there be too much pressure in the oil system causing the leak and excess oil in the fuel. The motor did not smoke much at all so I am really confused. Thanks
