Re: Primer ????
Having that RED lever over top of the solenoid, facing the other end of the solenoid is the automatic position. Facing away from the solenoid is the manual position.
Look upon this primer solenoid as a automatic/manual choke...... whereas you are operating it as a manual choke.
This primer solenoid, when operating properly is actuated by pressing the ignition switch key inward, which is the same thing as engaging a electric choke solenoid. Are you doing this?
If not, do so, and let us know what the results are. You can check the circuit and solenoid simply by having someone press the key in (engine not running/hood off) with the key in the ON position while you listen at that solenoid for a click.
