Inquiry (采购产品): piston rings for McCulloch chain saw motor I have a McCulloch chain saw. It worked good until I lent it to a guy who ran the oil out. It lost compression. Where can I buy rings for the motor? It's a neat saw and I was told it would be cheaper to buy a new one than to fix the old one. I will be thankful for any advice. Here's the info: Chain Saw: McCulloch MAC 3818 C213 Motor: CS 38CC SMHO38UB24A C213 Very Sincerely, William S.
