Took the engine right out. Cleaned cases checked reeds. Put it back together. New gaskets. Rebuilt cylinder New pistons and rings and spark plugs. Primed oil pump. Put 30-1 oil in the tank on the heat cycles. Put some more gas in to 50-1. Did 4 heat cycles. Started driving it. Put 9 miles on it and it piled up. Any ideas would be appreciated. Yes the pistons were in the right way. Rings were not upside down.
