I tried a new AM carb , nothing at all . Then a OEM carb with the pump fixed , 4 turns out it would start but not much more . Busy day today , may try again tomorrow .
When she does start can you get any revs out of her, can you scream the engine or blip the throttle for any length of time?
If your carby is good, do you think you've got a fuel flow problem? Are you always opening the tank cap between test attempts - that will let the pressure in the tank equalise. If you've got a bad vent then reopening the tank will each time let the carb get to suck a drop more fuel. A bad vent could be eliminated by getting her started and have someone keep her running while you slowly loosen the fuel cap to let the tank always be at atmospheric pressure.
Is fuel filter + line flowing ok? I suppose you could eliminate a blockage by removing the filter , blowing the pipe etc...
Just trying to think of how to eliminate a fuel flow issue as your problem.
