Thanks Ronnie

Answer
The clicking noise you hear coming from under the carb, is the fuel shut off valve. This is normal. By hearing that, you know that you have voltage on the primary system. You need to check voltage readings on the solenoid and the remote wire with the key switch in the start position as if you were trying to start the unit. This will let you know if it is the solenoid, or in the wiring before the solenoid. Back trace all your switches from there until you find the bad component.
