Well the paper under that Craftsman 3.7 wasn’t that old. 2009 local paper.
Still had a unsharpened Oregon 76 3/8 chain for back up and a 1/3 used 76 still on it in good shape.
Cool part on the 50/50 drawing I see here. It was the thin ring 3700 topend.
When I seen that bare piston without seeing ring yet I knew.![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
