Throttle Troubles

Postby Torson » Fri Jul 09, 2021 2:36 pm

The throttle on my Farmall Cub is behaving badly. I can start at a low idle, as I move the lever forward, I get no response. Only at the end of the arc do I get a big surge that later settles to a higher idle. The same happens when I try to decrease power. Any ideas? Thank you.

Lubricate ALL the pivot points from the throttle lever, through the governor to the carburetor. Then work the linkage back and forth until it moves freely.
