Re: Removing Stuck Pistons

[David Stanton]

I start by positioning the motor with the top of the cylinders facing upward. Put transmission fluid, liquid wrench penetrating oil, Kroil, or other suitable penetrating oil in so the tops of the Pistons are covered – some may run out the ports. Let it sit and every few days try to move the flywheel back and forth to free the rings and pistons. Moving back and forth is key, as it may not move all at once in one direction only. This works for most of the motors I’ve come across.
