    The carb bowl can be full with the fuel solenoid not working. The solenoid simply shuts off the fuel flow through the center jet. Remove the wires and remove the solenoid from the bottom of the bowl,reconnect the wires, then hold it against the engine to ground it, and turn the key to the run position, if the solenoid is working the plunger will retract into the solenoid body, if not try to lube it and work it back and forth manually. Then retest.

    Finally sorted problem turned out to be electrical on the ignition side thus no power getting to solenoid repaired broken connection behind battery(due to battery being loose)started first time many thanks
