Throttle Linkage Adjustment

On a '55 Model 60 gas (s/n 6048041) I've got a throttle rod (running between gov arm and carb) that puts A LOT of force on the carb throttle lever; so much force that it bends the throttle rod up till it almost touches the bottom of the fuel tank heat shield! This can't be good to put all that force against the bushings in the carb's throttle shaft)
If I loosen the lock nuts at the swivel on the governor arm and adjust to take out this "bend" and go to start the tractor the governor then "hunts".
If I adjust back in a little "bend" and start her up, the hunting problem goes away, but I can advance the speed control lever up quite a ways and the governor arm "sticks" until (I assume) the governor spring puts enough pull on it to cause it to go from idle to 800 rpm in a heartbeat. I can watch the governor arm "stick" and then finally release and "snap" the throttle rod to the proper position as I slowly advance the speed control lever!
I've gone through the Service Manual but came away more confused than educated! Any help on how to properly adjust the linkage from the speed control lever to the governor spring, and then from the governor arm to the carb would be GREATLY appreciated!
Thanks!

Al, Mike did a good job of explaining the governor rod adjustment so follow his adjustment procedure. ~I will just add some other things to check. Make sure the cotter pin that holds the throttle rod into the carb lever isn't too long or bent funny & hitting the carb casting [I have seen that cotter pin hang up & cause all kinds of throttle problems].
~Another thing you might have happening is after you adjust the throttle rods correctly the sliding spool inside the governor is then sliding on a new part of the governor shaft that it hasn�t traveled on in quite a few years & is sticking on the varnish & residue built up on the shaft, [that could be causing you sticking & hunting]. If after using Mikes adjustment the throttle still sticks & hunts, just run it for a while like that to see if it eventually clears up after the spool clears the shaft of build up�..

Al, I adjust the linkage a little differently than the manuals state but I get a more positive idle setting this way. Here's how to do it- with the engine shut off, open the throttle to wide-open position. Then, unhook the governor to carburetor rod and adjust it to one half hole short of reaching the governor arm. This is the factory recommended setting. However, I always set the rod a full hole short as the tractor is "snappier" at this setting. Once the governor to throttle rod is adjusted it need never be moved again, except if the carburetor or manifold is disturbed. Then adjust the throttle lever to governor spring linkage (or the throttle lever stop bolt) to get the fast idle speed, which is 1115 RPM for your 60. Adjust the idle speed at the carburetor. With this adjustment your tractor should open the carburetor at any speed just off of idle. For instance, if you have the throttle set at 700 RPM and suddenly need some power, the governor should be fully functioning even at this low speed. This is assuming the governor is in good shape. Many tractors I get in have been maladjusted and just doing this really wakes them up. Hope this helps. Mike

Mike,
Thanks for clearing that up. If I'm understanding you I want to pull the cotter pin and remove the ball joint assembly from the governor arm and adjust to come up short of the hole in the gov arm?
I think I was confused by which "hole" to come up "short of"! I guess it wouldn't make a difference, but I was trying to come up 1/2 hole short at the carb - made it a real challenge to adjust while standing on my head under the distributor with a 7/16" wrench!
Thanks again!

Al, it really doesn't matter which end of the rod is short. However, it is easier to make adjustments when you can see the hole and make the adjustment in the same place. Many John Deere tractor owners have never been around a governor that was "right" and adjusted correctly and assume they are ok when they really aren't. Mike

Mike,
I think it's a safe bet to put me in the "governor-impaired" group! : )
When at idle, should the governor spring be adjusted so it is just putting enough force against the gov arm to hold whatever idle speed I want when adjusted with the idle stop screw on the carb, or should there be a space between the gov arm and gov spring?
Thanks again!

Al, if the throttle rod to the carburetor is adjusted like I mentioned then this is not as big of a deal. If the throttle lever stop screw is adjusted for your engine speed (or the linkage from the lever to the governor lever is adjusted for the correct fast idle speed) then you need not do anything else. On the early model governor arms there is a boss that the spring will contact when all is adjusted correctly. On the later models with the "LP" type governor arm with the adjusting screw just adjust it to just contact the spring at slow idle. Mike

Mike & Clooney:
THANKS much for your assistance! It took me all of about 10 minutes to get it adjusted.
I love to think about all the money the advice I get on this forum has saved me in service calls from the local Deere dealer!
Much obliged, gentlemen!

Al in Iowa
