In Reply to: governor setting on H posted by Guyzoo on October 13, 2008 at 18:34:10:
The governor has no effect whatsoever on the rich idle condition. The governor only controls carb throttle plate position depending on the throttle handle setting and the RPM.
Therefore it appears you have 2 separate problems:
1 - Rich idle: The carb idle mixture is way out of adjustment. Or the carb is leaking internally and needs attention (rebuild).
2 - Idle RPMs to high: The governor to carb linkage adjustment (the adjustment you discovered beneath the sloped cover atop the governor) is not properly synchronized.
To synchronize the gov to the carb first remove the riser cover. Then remove small cotter pin from the pivot then pull the pivot pin from out of the adjusting block (don't drop the cotter pin into the governor!).
Now set the throttle handle to maximum speed. Next pull up on the adjusting block and on the carb throttle bellcrank and hold both parts there. When properly adjusted the pivot pin should slide easily into place. If it does not, loosen the locknut then turn the adjusting block up or down the threaded connecting rod as required. Then again hold both parts up and reinsert the pivot pin.
When properly synchronized you should be able to slow the idle RPMs low enough to stall the engine by turning out the idle stop screw on the carb.
