Any useful suggestions appreciated. Mike, If you are ABSOLUTELY SURE that there is a loose piece in the engine, it SHOULD NOT be run! if nothing else, it will shot-peen the living daylights out of all that soft aluminum we call a piston. It will also score the walls of the cylinder, bend valves, etc. I'm surprised that no one has been willing to tell you this. there is a catastrophe waiting to happen. The cylinder head must come off, even if just to inspect the damage. If, by chance, you were able to get the nut out of there intact, I wouldn't expect a normal service life from the engine. Good Luck!!!! Joe Savard Lake Orion, MI [Non-text portions of this message have been removed]
