I just picked up a first model 7032 60 and have started to clean it up. The rings are still good and stuck after 3 days in Hoppe # 9 gun cleaner and 3 more days in the anti-freeze crock pot. If I catch the end of the ring with the tip of an exacto blade and give a push there is no hint of movement. It's the 2 ring piston.

I know I can probably break them out, but I don't want to damage the piston grooves. Any other ring removal options out there? I haven't tried the oven.
