Subject: RE: Cold Seize Engine Trouble??

Fuel filter?? What fuel filter?? That engine has never had one, but will in the future. Certainly will have the mechanic check on these other possibilities, too.

Cold seize = Inadequately warmed up engine, leading to piston seize up.

My layman's understanding is that the pistons, being made of aluminum, heat up much faster than the engine block during a cold start. If the user puts the hammer down before the block has a chance to warm up, the heated piston can expand rapidly and seize up in the cylinder. Probably an oversimplification, but the message is clear: let the engine warm up sufficiently before really going at it. This may not be my problem, but still good practice to follow.
