On my 9N: If I shove the throttle all the way up; then pull down slowly, I can see that the linkage pretty much immediately starts to move the lever it's connected to on the governor. However, as I continue opening the throttle, the other lever on the governor, which is behind the first one, and which is connected to the carb, only moves a little bit. So at full throttle the engine only runs a little faster than at full idle. Is something wrong w/ my governor? Is it worth trying to fix, or would it make more sense to get a new one? Thank you...
 
First off if you post this in the 9N/2N/8N forum you will get more answers

That said it could be a linkage problem where the linkage binds up or it could be a spring problem or a gov problem. Govs can be rebuilt but if you remove your be sure to look at what bolt goes where or you will have problem since they are not all the same length
 
Common mechanical engine governors attempt to maintain a constant engine speed for a given load and throttle setting, and can only CLOSE the carburetor throttle butterfly. The governor SPRING is what actually fights the governor mechanism to OPEN the throttle butterfly.

So if it's not throttling UP properly either the governor SPRING is weak or broken, or the governor mechanism is gummed up, sticky, or binding, possibly due to worn parts/pivots/pins, etc..
 
Try this:

With the engine off, set the throttle lever to full speed.

Look at the carb throttle shaft. It should be in the wide open position.

If it's not, the linkage is out of adjustment or there is a problem with the governor.

If the carb is wide open, have an assistant start the engine while the lever is still in the full speed position while you watch the governor work. It should immediately bring the engine speed down to the governed speed, around 2000 RPM.

If the RPM is low, you will need to increase the tension on the governor spring until it comes up to specs. If too high, decrease the tension.

You can get more detailed adjustment procedures on the Ford N board.
 

First see how it responds to a load. Like without touching the throttle transition from nearly level going to up a steep hill.
 
Thanks guys. Sounds like my gov has done about all the governing it can. Given my mechanical abilities, I think it might be best for me to just put in a new one. Got one on order...
 
Be very sure which bolt goes where or you will find you will be learning a whole lot more about working in engines
