Choke questions

[spamn]

Engine: 1978 Merc 500
Controls: Black 2 lever Mercontrol

I am gone through my manual and cannot figure out some things with my choke.

First. My electric choke button on my Mercontrol won't work. I tested the solenoid by using a jumper from the starter solenoid and the plunger rose up as it should. Assuming that somewhere in my wiring, or even control box, there is a bad wire? How can I go about testing this. I have a multimeter.

Second. When I use the manual choke, the plunger stays in the solenoid. Therefore, when I push the manual choke down, the engine stays choked as the plunger is holding the linkage up still. The manual choke just has a piece of wire that is not firm enough to dislodge the plunger. After some research online, I think I may have found something. Is this engine supposed to have a choke spring that keeps tension down on the choke linkage? That sounds like it would help me out. If so, where does this spring mount?

Thanks in advance
Sam

Sam;

What is your s/n? Some of your previous posts talk about a 3 cylinder and some a four.

Re: Choke questions

Took the Mercontrol apart and found most wires to be garbage. Choke button had one completely frayed off. Just ran my own wire from the solenoid to the boat and installed a toggle switch.

Found a spring at Lowes and attached it to the linkage and then to the top of the lower carb.

Choke works like a charm now.
