The issue though is that my rebuilt 750 fuel pump seems not to be pulling fuel from the tank. All my gas hoses are new, I know the fuel line is clear, and I checked the banjo fitting at the gas tank, and it seem not to be leaking air (blew through it from the front and could not feel any leakage at the tank junction, and could hear gas bubbling in the tank). Fuel tank was boiled out and resealed, and I know the pickup pipe in the tank is clear.

So I'm wondering how long it ought to take for a 750 pump to pull fuel from the tank, and whether I need to prime the pump somehow. Or if there's something else I'm missing.

It was nice to hear it cough and try to run, so I know my distributor mini-overhaul worked, and that the carb sort of functions. Nice trail of black crud across the garage where it all blew out of the exhaust.

What I do is to put a little pressure to the fuel tank by using compressed air in the filler, and just close it holding a rag around the air gun (regulating pressure by how hard I push the rag against the filler opening). This primes fuel lines and pump, and from then on it all works nicely by itself.
