Why not end the guessing and beg, borrow, or steal a fuel pump pressure gauge? Tee it in between the pump and carb and observe the pressure while running. Should show somewhere around a couple of PSI. Gauges are not expensive, usually combined with a vacuum gauge (for cars). Not to be confused with high pressure gauges for fuel injected cars.
