DrAllis,I removed the bolts and cap screw
like you said and pulled the governor
assembly out.Everything looks fine to me
Weighs are in place,no loose parts or
pieces anywhere. Like I said before It
runs at low idle, but when I give it
throttle it goes crazy. What is my next
move. Thanks again,Don.

Leave it apart and pull the hand throttle half-way down. Go around to the generator side and grab the vertical governor arm behind the generator and work it back and forth/front to back to be sure nothing is sticking or binding in the governor linkage. Make sure the governor carrier for the thrust bearing is install correctly !! The ball bearing goes forward towards the radiator. Reassemble the governor and start the engine to be sure you have the ignition in "time". If it runs fine, shut it off. Place the throttle wide open. Remove the cotter pin on the governor link rod connected to the vertical governor arm behind the generator. Pull the link rod out of the vertical gov arm. The vertical governor arm should not move.....not one bit. If it moves rearward, you need to bend the link rod by pulling down on it in the middle to make it shorter. Keep bending it until the length is correct so it just slides back into the vertical governor arm. Test the results.

Hi,This is my first time so bear with me
How do I know if bearing carrier and
everything else is installed correctly
with ball bearing facing front of
tractor. I don't see a ball bearing.
Sorry I just don't have the knowledge.
That's why we have people like you.
Thanks.

The part in question has a smaller diameter end. Small diameter goes towards the radiator.

I followed your instructions, tractor
started, shut it off, vertical shaft
behind generator moved freely back and
forth, removed cutter pin and pulled
linkage rod out of vertical shaft.
Vertical shaft did not move. Linkage rod
slides in and out of vertical shaft very
easily. Same results. Did I do something
wrong. Thanks

WHEN REMOVING THE LINK ROD OUT OF THE VERTICAL ARM, THE THROTTLE MUST BE WIDE OPEN !!!!

DrAllis · Sep 1, 2020

Also, there cannot be ANYTHING connected to the vertical arm, link rod or carb throttle shaft. NOTHING. Some tractors get springs added to them because they don't know how to adjust the governor correctly. Cannot be anything connected to this linkage !!

handcrank · Sep 2, 2020

Can I assume that the governor is ok and
that the linkage is my problem? Back to
the beginning, the tractor ran fine when
I parked it last fall. When I started it
this year it revved up and I shut it off.
I found that the cotter key had come out
where the vertical shaft connects to the
carb linkage. I put it back in place and
the results where the same.Thats when I
asked for help.

DrAllis · Sep 2, 2020

I believe linkage somehow/someway is your problem. I could fix this tractor in 5 minutes if I could see it, but that isn't going to happen. So, lets see what we can figure out. #1. where the link rod connects to the vertical governor arm behind the generator, the cotter pin MUST be on the backside, so you really don't see it. If this is installed bass-ackwards, it could be binding at the carburetor end. If it is correctly installed, then look at the carb end. #2. The cotter pin there MUST be cut short and wound around the link rod both ways so it cannot come in contact with the carburetor in any way, or it could stick. #3. The throttle shaft arm on the carb cannot be loose on the end of the shaft, getting out of time or causing linkage to stick. #4. drop the carb down far enough to make sure both screws are in the throttle butterfly. If they are loose or one is missing, it could cause sticking when the engine is fired up.

When I remove the cutter pin from the
vertical governor arm, the rod that
connects to the carb flops back and forth
freely. There isn't any resistance in the
butterfly at all. I will drop the carb
and do as you say. Hope this helps.

DrAllis · Sep 3, 2020

Is the link rod installed correctly ??? Is the cotter pin on the carb trimmed short and wrapped around both ways so it cannot ever snag on anything ??

handcrank · Sep 4, 2020

Yes the link rod is installed correctly.
I dropped the carburetor and checked the
screws in the butterfly, both are tight.
With the throttle wide open and the rod
pushed all the way to the rear of the
tractor, the rod lacks about one half
inch from sliding into the vertical arm.
If I pull it toward the front of the
tractor, the rod goes past the vertical
arm hole the same amount. This is with
the throttle wide open.

handcrank · Sep 5, 2020

I bent the rod down until it slid into
the hole in the vertical arm. Tractor
started up at idle. Throttle has no
effect. I moved the lever up and down and
the tractor just idles.

DrAllis · Sep 5, 2020

Either I'm not explaining things good enough, or you aren't understanding my directions. One more time. Engine OFF. Hand throttle placed WIDE OPEN. Remove link rod from vertical governor arm. Force the now bent link rod to the REAR as far as it will go. While holding it fully rearward (the limit stop is built onto the carburetor) the length of the link rod should just allow you to slip it back into the hole while still holding rearward on it.

handcrank · Sep 6, 2020

This may sound strange but with the
throttle wide open and the link rod
connected to the carb pushed back toward
the rear of the tractor, and held there,
it lacks one half inch of going into hole
of the vertical governor arm. This is
after I straightened the rod. It,s like
the rod is half an inch to short. The
linkage rod is 12 inches long.

DrAllis · Sep 6, 2020

Either the arm on the carbs throttle shaft is loose on the end, OR the governor fork drive pin is loose allowing the vertical arm to be loose inside the fork. You have a linkage problem, because once that link rod length is adjusted, it does NOT change. That link rod cannot be too short. They are generally a bit too long and that's why we bend them to make them fit. 1/8" too long makes the governor lazy. 1/4" too long and the governor is really lazy and dead. Throttle shaft arm or governor fork pin.

handcrank · Sep 6, 2020

Can I remove the cover on the front of
the governor to check out the fork pin?
Hey I am eighty five years old and still
learning. Thanks for your patience.

DrAllis · Sep 7, 2020

With the link rod unhooked from the vertical governor arm AND the hand throttle WIDE OPEN, try to move the vertical arm forward and backwards 1/2". If the pin is loose in the fork, you should be able to move this vertical arm forwards and backwards a little, without stretching the governor spring. With the hand throttle WIDE OPEN, any time you move the vertical arm forward and release it, it should always return to the same exact place. If you try to move it rearward, it shouldn't move or change position.

handcrank · Sep 7, 2020

With the throttle wide open and the rod
unhooked from the vertical arm, I cannot
move the vertical arm even a little bit.
When I move the vertical arm forward
(toward the front of the tractor) the arm
comes right back. This is with the
throttle wide open. Does this mean
everything is ok inside the governor?

DrAllis · Sep 7, 2020

It means it doesn't appear to have any issue with the fork to vertical arm connection. I haven't seen the internal parts of the governor. You say they look fine. I've worked on these governors for more than 50 years. I've never had one I couldn't easily repair. I wish I could see yours because there's still something not right if it (as you say) still runs away wild.

handcrank · Sep 8, 2020

If I pulled it out and sent you some
photos, would that help? I will review
everything that you've told me to see if
I've overlooked anything.
