DO NOT take the plug wires off if your pulling the fuel line off. That's a fire waiting to happen if you start cranking it over.
Do what others have said. Take the fuel line off the carb and crank it to see if fuel flow is there. If it is then the carb is blocked with fuel varnish. If you still don't have flow. Work your way to the tank.
