I have an MS440 that had bad rings. I pulled the cylinder and removed the old rings and cleaned the carbon from the ring grooves. I then installed new caber rings. Using a ring compressor, I cannot get the piston and rings to go into the cylinder. I have replaced rings several times before and have not had any problems. The piston does into the cylinder fine without rings. The ring gap is .008" with the ring about 1/2" below the bottom edge of the cylinder (gasket surface). What could be wrong? thanks
