Seems like the fuel is collecting in the crankcase and not making it to the top of the Piston. Any explanations?
Never worked on that motor but does it have reeds in it? You might want to pull the pulse line and crank the motor and check for pulse, i have seen pulse lines fill with fuel or oil for that matter and not pull fuel. And if u put your hand over the carb inlet and crank u should feel u pull on your hand.
No Reeds. I am getting fuel in the pulse line. Seems to be coming from engine side though. I don't find any leaks in the pump.
