WD45 Governor Adj ?

Question - On the top of my WD45 governor is an adjustable set screw. I've looked through my manuals and I can't find any reference for it.

What does it do when screwed in or out?

Tractor runs great except for the fact that it does not achieve full rated RPM - carb travel is smooth and has plenty of room to move further. I have adjusted all linkages and it still remains low. The governor does regulate when under a load.

I appreciate your thoughts,
Gary

if the screws on top of the spring cover .which has four 7/16 headed screws holding it on . its a gleaner cover . the set screw pushes down on the arm not allowing the spring to be stretched as far open as it can lowering the rpms .

Many thanks for your response. I believe you are correct, just no detail in any manual.

Thanks,
Gary

Gary, I know you said you checked all linkages does this include the gov. control arm also? The cross shaft as its called should be adjusted to fit correctly with the carb. linkage.Unhook the carb linkage from the gov. arm, then open the hand throttle all the way, now open the carb. all the way with the linkage rod on it. The carb linkage should be 1/3 to long to fit in the gov. arm hole, this will give the gov. the "preload" it needs to function proper. Good luck, Hoss

I appreciate your response. Affirmative, I did exactly as you and the manual details with the linkage. As far as I can see, the governor is the culprit in holding it back. The set screw looks like it would affect the preload to the governor but no info can be found. I did some adjustments with it and found no effect - possibly something broken?
