I can't seem to get the governor adjusted properly on my 1946 JD LA. Any help and a printout of it would be greatly appreciated. Pics are always good too.

What is the tractor doing now,is it up an
running. The cable on them runs to the
bottom of the governor to a spring. Then
the little rod is on top of the governor
to the carb. The top rod should be
pushing the carb back so it idles. If not
u need to adjust it so it does when the
tractor is running. If it is running to
fast turn the carb screw on the stop of
the carb butterfly. If it's still runs
fast then the carb shafts are sucking in
air and need fixing. I would post some
pictures when I can figure on how to do
it.

I don't think my la has that flat piece
of flat with the bolt in it in the middle
of the arm and cable holder. I'm thinking
the arm looks like it would hit it an not
let it throttLe up. On the LA u pull back
on the thottle rod for faster engine
rpms. Let us know more an we will get you
going .

I just looked at the one in the shed and it is hooked up the same as your. What is yours doing. Runs to fast or will not run up on rpms.

Depending on how i hook up the linkage to the carb throttle it either just idles or it runs almost wide open. I can't seem to find an happy medium

I would check and see that them two arms on the governor move by them selves. With the motor off pull the throttle rod back and see if the one to the carb is free and move back and forth. If not them to are stuck together and need to be free. The one arm with the cable to it pull against that spring and the other runs with the governor to make it run at a set rpm. If them to are loose then when the motor running and you push the carb open some there should be pressure on the arm pushing it back to idle. If there is to much play in that rod to the carb from the governor the motor will run fast so you need to adjust that rod so there good pressure pushing the rod to the carb back when running . What I like to do on them is I have the linkage loose on there with the cotter pin out and adjust the rod to put pressure from the governor to the carb with the motor running at idle. Let us know what you find out.

I had a bind in the brass piece on the throttle rod cuz it was on backwards. I did it not knowing how it was supposed to go. Live and learn. The governor is back in office now working again
