  • AMC 150 Nutter Bypass

    The computer died

    Did the nutter bypass it will start and run
    very rich with no power
    Without the computer how do I set the Stepper motor
    And adjust the carburetor

    Also have been told the distributor springs are too strong
    Should they be replaced if so with what
    How should the distributor vacuum be connected

    Any more information would be helpful

    Did the Nutter on my 4 cyl before it died.

    You will have to remove the stepper and physically extend the needle all the way, then reinstall.

    The dizzy vacuum shouldn't change, at all from the original, but if you don't have the original setup, then you will need to connect it to a metered vacuum port on the carb (no or little vacuum at idle, then increases with throttle travel )

    Don't know much about the stock dizzy springs, but the replacements should be available through Mr. Gasket, same as a ford V8.
