I started with a primer bulb 2152 for this build. It has a 44.3mm 346xp/2153 cylinder and new meteor piston. The carb has a fresh rebuild, and all of the fuel lines are new. No base gasket, the stock muffler opening has been enlarged, and the timing advanced. The decomp port is plugged. It runs pretty well, the vid is cutting dead Elm with an 18" safety chain. The only blemish is 1/2 of the top fin is missing on the jug and the second one is welded. I have more pics of the build if a buyer is interested. I'm looking for $350 for this one.
This is the same saw that I had for sale in the "50cc madness" thread. I put a couple of tanks on it since then. The primer return line was a little soft and folded over where it turns to attach to the tank. I noticed it was spraying a little fuel in the carb box when pressed while I was using it. The new return line solved that issue.
