If you are in fact getting fuel to the carb, and the engine tries to run when offered carb cleaner, the fuel solenoid is highly suspect.
Test the wiring that goes to the solenoid to see if it is getting 12 volts when key is in the run position.
Often, you may hear the fuel solenoid click when key is turned on.
If your fuel solenoid has a ground wire serving it, be sure the connections for the ground are nice and clean and tight too.
