Bruce,
This one's a little hard to explain how it looks and works via email. I wasn't fully able to understand it until I had the picture from the parts manual and the serice and repair description from the service manual, both open in front of me while I had the old parts in hand. Assuming you're talking about the gasZ134 Continental engine. If diesel, this probably doesn't apply! The assembly is inside the timing cover at the front of the engine. The assembly consists of a smallish plate shaped like a pie plate, with a shaft sticking out of the middle and a race with some ball bearings circling the shaft. The assembly sticks into the end of the cam? crank? (Don't remember). As engine speed increases, centrifugal force pushes the ball bearings outward. They push/pull on the lip of the "Pie plate" as engine speed increases/decreases. This push/pull is transmitted via a lever through the timing cover. From there it's linked via rods, etc. to the carburetor. I believe there's a screw adj. on the lever going through the timing plate, and also believe there's some linkage rod adjustment that can be done to alleviate some of the symptoms you describe, just don't recall off the top of my head. Really need the service manual at a minimum for that one. Adjustment may not be enough-not uncommon for the pie-plate and bearing balls to wear out and come out as separate pieces when dissasembling. The worst part of that job is removing the front end, heavy bugger. Maybe someone smarter than me can tell you how to do it w/out removing, but I don't think so. Also, if it comes to replacement, my aftermarket governor had the smallest burr on the shaft, right above where it's welded to the plate, rendered it useless. Assembled and dissasemble about 3 times before we found and cleaned up the burr, works great. Best of luck, 202's rule!
