On another note, tires are becoming a challenge to locate. I've found a pair of 7.50x20's but need 4 more. I'd like to buy a matching set of 6. I'll probably have to order them. Are bias ply tires the only tires that will mount on the old split rims? None of the tire shops here in AK suggest anything but bias ply on those old wheels.

If the rings are stuck hard in the piston lands they can easily break and score a cylinder . If the comp. is down when the engine is warm that is a sign of stuck rings. I believe Ron was trying to save you from maybe damaging the motor.
