Farmall C Governor Adjustment?

You dont adjust he gov except for top engine speed but you do need to adjust the linkage from the gov to the carb correct or it will not respond to throttle very good and may not aidle slow or even reach top rpms.
 
There are three things you can do.

1. Time the governor to the carb. Disconnect the carburetor throttle rod clevis from the governor arm. Tractor off, set the throttle lever to full throttle. Adjust the length of the throttle rod by turning the clevis until the pin slips through easily with the carburetor throttle pulled wide open.

2. Adjust the reaction spring. Rev the tractor from idle to full. It should snap right to, with no "bounce" to the RPM. If it bounces, you need to remove the acorn nut from the bottom of the governor, loosen the lock nut, and turn the screw in 1/8 to 1/4 turn at a time until the engine revs up to full RPM with one RPM bounce at most. If the engine surges at full throttle, you need to turn this screw OUT 1/8 to 1/4 turn at a time until you find a happy medium.

3. Adjust the high idle RPM. This is the screw on the top of the governor. Out is more RPMs. In is less RPMs. It should run at, I think, 1600RPM wide open with no load.
