I have a 1924 J motor with a stuck rear piston. I removed the front cylinder with no problems. This is a side project that I'm in no hurry to rebuild. I removed the spark plug several years ago and spray Kroil, PB Blaster, or whatever I have in my hand, into the chamber every so many months. It has cast iron pistons. Any ideas ? Or should I keep doing what I have been doing ?
