We have here a used Vintage OEM Factory McCulloch 400 450 Chainsaw Cylinder Ported. This cylinder came from the estate of vintage racing kart restorer and fabricator Tom Smith. Being sold as-is no returns. I'm not 100 percent if it's ready to go or not. One fin is cracked, but has not broke off. Doesn't appear to be any cracks other then the fin.

If you have any questions, please free to ask. Thanks for looking!
