Also, while you have the plugs out, observe thier condition. They can tell you a lot.<br />They should be black, but not 'tarry'.If they are, wet and fouled, and the compression test checks-out good,simply change them out and run the engine to see if fouled plugs were the cause.Plugs are good for about 80 hours, and less if you run the engine rich (like me).<br /><br />A super clean looking plug means water. On this engine, exaust port plates tend to warp over practicly nothing, thus leakiong past the gaskets.<br />But Yepblaze has best advice to start with.
