Spray all connections with your favorite penetrating lubricant and keep working the linkage back and forth.

The governor. Perhaps it is binding internally.

The rod from the control lever attaches to a short arm at the front end. That arm is one end of an "L" shaped part. The other end is attached to the governor spring. The part pivots on a peg that sticks out from the governor housing. The "L" shaped piece commonly gets stuck on the peg. Squirt some penetrant, trying to get it on the peg. Work the arm back and forth to loosen it. Be gentle, the "L" shaped part is very easy to break. This is easier to do (and see) with the hood off. But you can do it with the hood in place.

Hi,
Here is a page from the Cub parts book showing the governor and other parts. Number 11 in the pic gets stuck on number 12, is what usually happens.
The owner's manual says oil the linkages so they work freely. You will need to use the penetrating oil, like they said above. It may take some time to get it loose. :)
