Is it possible for fuel pump to have enough to prime the carby but not enough to keep it running, gave pump 4 good pushes and delivered a good shot each time.
Sounds like a shot balast resistor or the wire from the ignition to the balast resistor to the coil.
If its firing when you turn the ignition key to start then stoping usually with a backfire when you turn the key bakc to the on position then 99% of the time it's one of these two items.
Also if you have a 12volt coil (ie does not need a balast resistor) then make sure you bypass or remove the balast resistor as it will not run.
