1961 Briggs and Stratton 3HP horizontal shaft engine, Model 80252 - Governor Springs

Ok, but if I insert the spring into the same holes on each end of the linkage, wouldn't that negate the effect of the spring?

 

[Rivets]

That spring is there to keep constant tension between the air vane and throttle. It is used to help make sure that when the vane moves, the throttle reacts as quick as possible, no lagging behind.

I believe Rivets is telling you to replace (place) them here..! see photo red arrows.

Observation seems to indicate that when the operator moves the control from slow to fast, the larger spring should stretch while the smaller spring relaxes. When the operator moves the control from fast to slow, the larger spring relaxes while the smaller spring begins to stretch to help pull the throttle closed at idle. So if I insert the smaller spring in the holes suggested by Riverts/EngineMan, wouldn't the spring always stay the same length as the rod, thus having no effect on the throttle itself? Should the end of the smaller spring near the air vane, be connected e.g. 1) in the same hole as the larger spring on the air vane or 2) perhaps to the loop of the large spring near the air vane or 3) perhaps to some other spot which currently eludes me, in order to help keep the throttle closed when set to idle?

that spring is to eliminate binding of the linkage,if im not too far off,

Going by the parts manual....!

 

[Fish]

Yeah, I have argued with a few Briggs folk, that spring is pretty much useless.... I never worried about it or replaced it....

I shoudve read this more closely before I chimed in my 2 cents,( I welcome btw,when im told im wrong or full of it,im here to learn from the pro's)

I think I was way off,and none of you older guys will hurt my feelings in telling me so,

Maybe I didn't explain the use of that spring to well, I'll try again. That is not a governor spring, it is an "anti-flutter" spring and is not absolutely necessary. But, the spring connects at each end of the link in a hole near the link holes - one on the throttle shaft (on the carburetor) and the other on the governor arm. If you see no tiny holes immediately next to the linkage holes then simply insert the spring into the same holes as the link goes into. The purpose of this spring is to keep the tension tight between linkage and it's respective mounting points. I doubt if you'll notice a difference without this spring, unless you want it to run extremely smooth at idle.
