Just installed a several year old Evo 46 in my SSE and test ran today. Problem was not that it would not run, but that it would not shut down even with the throttle completely closed. Obviously I have an air leak and it probably is in the fuel tank or lines but during inspection, i found a puddle of after run oil on the table just below the front of the engine, apparently coming from the front bearing. Does this bearing/seal commonly go bad and would it suck enough air to keep engine running with completely closed throttle? i have just rebuilt the plane and thought I had replaced all the fuel lines, etc. Will pull tank and retest all connections.
