did you adjust the idle adjustment and fuel-air mix on the carb? It still sounds as if it is in the linkage and carb adjustments and not the governor.

There is the throttle idle stop screw on the air intake side and an idle adjustment screw on the fuel inlet side. It sounds like the stop screw air side it is just open to prevent stalling. The ideal adjustment screw ( fuel side) is all the way in and one turn out

I adjusted the rod from the governor to the operators station and I got the tractor to idle down. I got the idle set at 610 but when I give it throttle the most I get a full throttle is around 930. I have checked the carb to governor adjustment several times and I’m 100% sure it’s correct. I got play on the spring on the inside. It doesn’t seem worn out but maybe it is. The top screw on the governor is screwed all the way out and the throttle on the carb is wide open. It’s a brand new Factory Zenith carb by the way. I’m about 7/8 out on my adjustment screw.

What would you like a picture of. The governor linkage on this 140 doesn’t seem as responsive as the governor on my cub when both tractors are not running.

With the engine running at full throttle on the hand throttle you are at 930 rpm.

can you move the linkage at the carb by hand to increase rpm?

If yes the link is still off.

If not the idle set screw is limiting the governor

I will try to take some pictures or video tomorrow. I have a 140 with a tach

Yes I’m at 930 rpms. Checked with a otc photo tach. I got three notches left on the throttle but it won’t go any further. I tried it with the rod unhooked from the hand throttle to the governor with the same results.

First, adjust the governor to carb. linkage according to the manual, then give it no more thought. You say your governor speed adjust screw is backed off fully but is the lever making contact with it. If yes, replace your weak governor spring.

No the screw at the top is not making contact with the lever on the inside. I ordered a new spring last night. It just seems like to much play in it for it to work correctly. I bought the tractor as a non runner so I have no idea about it’s past. But I got it for half of what everyone else is asking for a running tractor.

My throttle lever is a little off-center adjustment-wise. I can move it back to past the notches and only get to about 3 front the front for max.

The RPM range is from about 600 to max 1500.

I did not see any threaded rod in view in the clevis. I looked at my other 140 and it looked similar

Hope this helps

What about the screw on top of the governor. Do you screw it in to increase high side rpms.

I do not remember adjusting it. The PO repainted. I do not see any wrench marks on the bolt or jam nut.

I tried adjusting mine and it made no difference. Hopefully my new parts get here Friday.

I put the spring in and now I can get my top end rpms but I can’t seem to get the idle down below 700. I have tried every combination I can think of. Any ideas from here.

for the low end I would focus on the carb adjustments like idle set screw and

I had one doing the same issue, had to pull the governor to replace the inside spring, all was well after that
