It may have an anti-backfire solenoid on bottom of carb bowl that is not working.

38racing is correct. Have you confirmed gas to the carb? I mean actually see a steady flow of fuel.
If so, remove the bowl. Does it have gas in it?
Hold your hand over the throat of the carb as you turn it over and see if it will suck some gas through.
If you can't get gas through and there is fuel in the bowl, rebuild or give it a really good cleaning.

you might even be getting fuel to the bowl but the bad anti-fire solenoid might prevent it from getting into the fuel nozzle/jet.
