Throttle Linkage Stuck - SUCCESS

[Barnyard]

When the tractor is off the linkage moves as it normally should. I have timed the governor to the carb and it is very easy to move. But when it is running, the linkage goes into a bind. What am I missing?

[RonT]

If it's binding in the idle direction, I would look at an internal problem in the Gov or the set screw. If the spring tension is too low (or lost) or there is something causing the weights to bind in the outer configuration it could cause this.
I don't have specific knowledge of the cub governor system but encounter this occasionally on Hit n MIss engines.

Ron, it puts the carb in full throttle whenever I start it no matter where I actually have the throttle set.

Have it at the Barnyard Bash and I will take a look at it.

[Bob McCarty]

I agree with Ron. Something internal, weights rubbing, thrust bearing shot, etc.

It'll be here, Ted!

[Dale Finch]

As a quick look, might pull the bumper spring and take a peek at the fork inside. I was working on mine a couple weeks ago, and was surprised I could actually see it with a mirror and flashlight. At least it's an easy thing to check and possibly eliminate as a problem.

Hey, can we have a "Zoom Bash" if we are still under travel restrictions at the end of May?! Of course, I guess that would require my learning how to do Zoom!!

[Jim Becker]

You don't have the throttle plate connected to the choke rod and vice versa?

Agree with Jim. Throttle and choke connections at carburetor reversed.

[Barnyard]

No, but you made me look.

While I was running it I found that it also wouldn’t run unless the choke was out. I’m gonna swap carbs until I have time to go through the one on it.

FWIW
When l first joined this group it was because l had a governor problem. It would idle at low throttle, but advance it jus 2 notches and it would take off, building rpm like a jet engine.
Long and short. What a mechanic friend and l discovered eventually, was that the pin that attaches the weights to the shaft had worked it's way out. So the shaft was spinning but the weights weren't doing their job.
If anyone needs more detail, l'll be happy to share.
Just throwing it out there.

It is extremely rare to see that with the pin. It is almost never the governor insides. Linkage yes, but you should check and recheck a lot of other things before you say it is the governor and take it off. I think the governor is the most reliable system/part on the Cub. That is was a good mechanic.

Carb, air leaks, linkage binding, reversed linkages as mentioned, proper fuel flow to the carb, messed up keyway on the cross-link, plus some I can not think of right now, before the governor insides.

Bill, while working on the governor, did you have the cross shaft off of the governor shaft? If so, you may have lost that little woodruff key. Years ago, I had one shear and it acted much like that.

I'll help too . coppersmythe...................

Gary, the only thing I did with the governor was time it to the carb. I nevr took anything off.
