I have a 1992 force 120 hp. once the engine reaches 3000rpm there is a metal scratching noise which leaves after 3300 or so and sounds fine from then on up. Would this be some sort of pinking noise? Plugs look fine
i'm replacing the cylinder head gasket on my 120hp 1993 force. Can anybody tell me the correct torque settings for re-attaching the plate and also i've heard that you should replace the bolts with new one's. Is this necessary?
