Dieseling

How do you stop it from dieseling whin you turn off the key?

Your idle cutoff solenoid is probably broken or the wire has come loose.

"On the side of the carburetor body is a barrel-shaped object, a little larger a pen-light battery, with a black wire connected to the outer end. This is the idle fuel cutoff valve (solenoid). On older model carburetors it s on the right side, and on later models it s on the left, close to the throttle arm. This valve shuts off the flow of fuel when you turn off the engine, to prevent "running on." Be sure the wire is connected and that it runs to the (+) terminal on the coil. (Also attached to this terminal is the black wire that provides power to the automatic choke.) Make sure that the idle cutoff valve is screwed into the carburetor snuggly, and not rattling loose. Don t overtighten it though, it s got a fine brass thread and screws into aluminum - both relatively soft metals.

Note: You can test the operation of the idle cutoff valve solenoid very easily. Turn on the ignition (don t start the car), and pull off the wire on the solenoid. Touch the wire back onto the connector, and you should hear a clicking sound as the valve inside moves. If you do not hear a clicking sound, check to make sure there is power (12 volts) to the wire (small trouble light, voltmeter, etc.). Replace the solenoid if necessary. If it s not working, you won t get a proper idle, and you ll get rough running at traffic speeds, too."

Think you for the help.
