[QUOTE="PawPaw, post: 228737, member: 1934"] I agree that having the cylinder fixed is the best cure, but....The portion of the cylinder that is damaged never has the piston rings come in contact with it and thus there would be no loss of compression. You may want to sand and emery that are to make sure there are no sharp edges left and the put a new piston and rings in in to see if it will run ok. The issue will to see if the bad cylinder damages the piston skirt. Paw Paw [/QUOTE]
