  • 8N motor not decelerating
  • 1949 front distributor, 6V 8N. Started tractor recently and accelerated with throttle as per normal operation. When I tried to slow motor down, there was no response using throttle. I had to pull back on the inner (toward engine block) of the two levers on the distributor to slow down the motor. Turned off the motor and restarted with the same outcome several times. Checked the throttle linkage, nothing missing or disconnected. Does this indicate itís time to rebuild the governor, and if so, which part(s) would be needed? Thanks for your thoughts.

  • Thanks all for your thoughts and suggestions. Iíll start with a good carb cleaning, focusing on the linkages. Merry Christmas.

  • Rick, if you determine that you need to overhaul your governor, we have an excellent tutorial here in our How-To's library that will walk you through the process.

    Merry Christmas.............Ed

  • Parts needed? The broken ones starting with the big fat round ones. All 4 of those.
    Maybe I will get batteries for my crystal ball this Christmas. Then I can get you the answer from inside the device.

  • The throttle shaft in the carburetor could be gummed up and won't return on its own. If that is the problem, remove the carb, remove the throttle shaft and clean so it will rotate freely. Just had that to happen on a 51 8n a couple weeks ago. If that is not the problem move on to governor.
    Good luck, post back with what you found and Merry Christmas.
