Ford 601 governor questions

Is there anyway that a governor that not working properly or out of adjustment would drastically affect engine power? Or is it strictly related to speed and engine rpms going up and down? When my tractor is pulling the bush hog it will bog down some and seem to rev just a little higher and come out of being bogged down when the grass isn't noticeably shorter or less thick. Doesn't always do this and maybe it is due to entering a thinner area of grass but I wanted to ask about it. It does maintain a consistent speed and rpm most off the time. especially when there is no load on it. When the throttle is closed all of the way at an idle, I can open it 1/4-1/3 before the engine starts to pick up rpms. Does this mean when it is opened all of the way that it may not be a full engine rpms?
Also, can anyone tell me how the compensating spring goes on? It is not the spring near the fan, it is the spring just above the disc with the spider compression washer on top that is under the battery I have the spring but can't figure out how it goes on. Sorry for so many questions, but the engine or pretty worn down on this tractor, Im trying to figure out if there is anyway I can get good enough performance out of it without putting for money into it just to find out that I'll have to sell it at a total loss. Here is what the compensating spring looks like.

remember, your hand throttle goes to the gov, and the gov goes to the throttle plate on the carb.

you set the rpm via the hand throttle and it will keep that rpm by keeping the throttle plate at that position, at that LOAD. if you increase the load, the governor will attempt to keep that rpm by moving the throttle plate to let more fuel in.


not uncommon to slightly overrev if comming from a hard laod to no load instantly.. loose linkage will magnify this.

if the gov is snatching the hand throttle down, check your comp spring.

if you have a lean situation, perhaps from fuel starvation, you can get a hunting governor that seems to over rev, then stall back.

Thanks for the replies! I will find somewhere on the battery tray for it. I dont think the fuel is too lean. Ive had a had time trying to find the perfect spot the the big main adjusting screw on the carburetor, since they say to adjust it while running in the field under load. can't really do that without stopping everything and then gearing it all back up to speed.
