I think I isolated my problem. Basically fuel isn't pumping to the engine. When I remove the fuel line from the high speed needle, fuel flows when I turn the engine. When I hook it up again nothing flows. Could the high speed needle be blocked? How do I unclog it? Or could it be another problem? Since nitro fuel spits out of the fuel line when it's not hooked up to the HSN, I assume it's the problem. My tank seems okay and sealed properly.
