Apparently there is more to this thread somewhere else. More info would help. From the info here I sort of doubt that the solenoid could be that far out of adjustment and the anti dieseling portion of the solenoid only picks up for 6 seconds after the key is in the off position. I would check the position of the needle in the piston. The little plastic ring should be flush with the bottom of the piston. Also a big problem with this carb is severe cracking of the rubber base mount. If you provide more detailed info, I can provide a better diagnosis. You may even have a brake booster hose disconnected.
