Farmall cub

I asked a question on Sat about a governor on a cub. Can the rpms be adjusted on the governor? full throttle rpms are way to low. It seems to be adjustable, but I don't just start turning things.

Sorry nobody has replied.
Go to farmall cub.com and there's some good info, plus downloadable manuals there. Step by step details on how to adjust your governor. Start with the linkage to carb adjustment first.
All the best with it.

There's an adjustment but it's not a very wide adjustment. Only 100 RPMs in either direction of "right."

It's the screw on the top. Loosen the jamb nut and turn the bolt out a little at a time. It probably won't help much if at all.

First off the RPMs on a Cub are only supposed to be like 1580 or something like that. It's there on the serial tag. They're a low RPM engine, and quiet, so it's going to sound like they're doing much.

If you shine a light in from the left side you will see a spring. Those can get stretched out and prevent the engine from getting to full RPM. If it's stretched replace it with a new one from a CaseIH dealer. IIRC someone mentioned that yesterday.

Not every problem can be "adjusted away."
