1973 Ford 2000 3cyl gas GOVERNOR PROBLEM

trucol · Aug 27, 2019

I have a 1973 Ford 2000 3cyl gas burner. I was cutting grass, and all of a sudden the engine revved up extremely high. I was as if my governor just quit working all of a sudden. I don't know anything about how the governor works, and I cant locate my operators manual.
The throttle linkage and springs seem to be intact. The linkage is attached to a lever on the front of the engine.
I constantly have to 'ride' the throttle lever to keep it from revving too fast. Can someone please help me out with this?

Does the other end of the rod that is attached to the lever attach to the arm for the throttle butterfly? Does the lever move as the RPMs increase or decrease?

It does.

If the tractor is left idling, the RPMs will increase to wide open.

Those governors are pretty simple
actually and I don't know why they go
haywire sometimes. I do know they are
lubed by a small metal tube that comes
out of the block and connects to the
underside of the governor body. If they
are not recieving oil that can cause
problems. I would crack the fitting on
the tube and with the engine running see
if it leaks oil. Let us know what you
find there.
That tube is short and stiff so it may
not leak unless you wiggle it a bit.
I would not try to remove the tube -
it's hard to replace - Just wiggle it
to loosen the connection a little to
insure it leaks.
I also know there was an older, two arm
governor and newer 1 arm type. Your 1973
tractor would have the new type. All the
throttle linkages back to the bell crank
on the intake manifold and to the
carburator are different so if you end
up buying parts get the new type as the
linkages will not interchange unless you
get everything together.
Photo shows the little tube.

Is the throttle hand lever easy to move back and forth? Check the friction disk at the bottom of the shaft. They can wear out or the spring could be loose.

Thanks, Ultradog. I'll try that. It may take a couple of days before I can do it. What do I do if there is no oil there?

Thanks, Mike. The throttle linkage works fine, and the friction disk and spring seem to be ok. It just started revving up all of a sudden, like you flicked a switch!

I found this photo while looking for something else today.
It shows the fly balls and bell from the governor.
If the governor is lacking oil the shaft that the bell is hooked to will get gummed up and stick.
It should slide freely in/out on the shaft.I hope this stupid modern view works.

WOW! Thanks Ultradog! That's the only view of the governor I've seen. I do believe it will help.
