I crashed a plane with an OS FS 91 Surpass with Pump. I found it 5 months later and went thru the engine, cleaned it and put in new bearings. I am not able to get fuel into the carb. The pump draws fuel in and out but nothing will go into the carb. I am not able to blow air thru the inlet nipple or aspirate thru it. Diclaimer: I had to soak the carb in fuel for a week to get the throttle barrel loose but there were no signs of corrosion. Help
