1951 farmall c governor issues

I have a 1951 farmall c, I just installed engine, got it running and noticed it won't go full throttle. the lever for the throttle won't go forward far enough for full throttle and see no adjustment at governor. I noticed about 1" of play at governor where the throttle rod would hook to governor and the rod that would hook to governor on other side to attach to carburetor. Is this amount of play normal? Something tells me I need to remove governor and look inside governor for worn parts? Any suggestions would be greatly appreciated. thanks for your time.
 
There is a kit available through Steiners Catalog,There was a good write up on that exact gov in the last issue of Red Power Magazine by the Tractor Doctor.
 
If you just rebuilt the engine, I would rebuild the governor also. I did the governor on my C and it did need some attention. Inspect the thrust bearing that rides on the governor gear an make sure it is in good shape. There is also a nylon bushing that rides on the governor fingers that can wear so look at that. Also on the right side of the governor at the carb linkage connection end there is a small bearing that should be replaced. This bearing doesn't get much oil and will seize up. All the parts are still available from many sources. If you don't have a manual there are exploded parts diagrams on the Case/IH web site.

Good Luck

"no adjustment at governor"

Yes, there is, there's an upward-facing bolt with a lock nut on it on top of the governor that sets the high speed limit. Screw it "in" and forward throttle lever motion and high engine speed is limited, screw it out and the throttle lever will be able to move farther forward and engine high idle will increase.

The two levers on the governor are not directly connected, some "lost motion" between them is perfectly normal.

There's not NEARLY as much "magic" involved in basic governor action as some would like to have you believe.

The governor spring tries to pull the carburetor throttle butterfly wide open as soon as the throttle lever is advanced, centrifugal force acting on the governor weights counters that force and tries to close the butterfly. For a given throttle lever setting, the engine speed at which those two forces are equal is the speed at which the engine will run.

If the engine won't rev up at all with the advancing of the throttle lever, the spring is likely broken or disconnected, if it won't quite reach "rated speed" the spring may have stretched/weakened a bit with age, which in my experience is not as common as some others say, but possible.

Putting the spring aside, most other governor issues will either cause a slow governor response to "pick up the load" or engine "runaway" if there's a failure in the area of the weights or weight fingers, the thrust bearing and sleeve, or the "governor fork".
