Can I bench test my carb to make sure it is working ?

Hi fellow early bayers !

I have been having issues with my carb for my 1600 engine, and have taken it off to clean and check it all. I have done that and I set it up on a wee rig on my bench which supplied it with fuel. Fuel is getting to the chamber and is being cut off, good. When I connected a 12v battery to the fuel supply cut off and an earth to the carb and opened the valve I tried pumping fuel through the carb using the throttle lever however nothing is coming out of the tube injector at the top.. My question is should fuel be coming out this tube when I pump it and the fuel cut off is working ? Thanks very much

Fuel cut off only closes the idle jet, accelerator pump (what you are talking about) works all the time. Check the ball valve and diaphragm are okay.
