I am fixing this 1-93 for Igpoe in trade for a nice Super Wizz 66. I started by just putting a new kit in the flatback carb and installing new fuel lines. That was a no go.:angry: After digging into it some more I noticed that the block was replaced at one time because ther was no yellow paint on it anywhere. Piston and cylinder look awesome, and a thin ring piston too. I ended up making a new stuffer gasket and all new intake gaskets. After reassembling everything with all new gaskets the carb still will not pump fuel from the tank. My thinking behind making all new gaskets was to eliminate the possibility of an impulse tract leak. I'm thinking that the problem still lies in the carb, but I'm going to pressure test the engine now. The only locations left that could possibly be sucking air is the crank seals and where the flywheel side of the crankcase bolts to the engine block. Well here are some pics. I'm giving up for the night. My new gaskets that I made.
