I have a similar problem on my monza. It takes a lot of cranking to get it started. That's because the fuel has evaporated from the carb. Your problem could be cured by using an electric fuel pump, that has a prime switch in the elctrical circuit. The monza has an electrical pump in the fuel tank, but only works under the "start" cycle, or when the oil pressure light is off with the key in the "run" position. So it takes a while for the fuel to get to the carb from the tank. To test my premise, pull the air cleaner off the carb, hold the choke open and manually open the throttle to see if there is fuel squirting in the venturi from the accelerator pump.
