Following further adjustment on the carb main and idle jets, if I'm still getting uneven performance, would it be advisable to try a different spring hole on either shaft?
This is a new engine.. I would double check that the governor was adjusted to begin with. Many times after rebuild, builders just set it close. Its easy to check tho.

How do I do that, other than what I already did - which is to loosen the arm, turn the shaft and the arm all the way ccw, and then retighten. I'm told that if the carb is wide open, then it's set (?) More to do than that?

No, You did it correctly. The spring sets the sensitivity. But from what you described you have it in the correct position. Im sure you said this but are you using a new carb? or the original one?

You know it takes 3 hands to do that governor adjustment don't you? One to hold the carb open, one to turn the shaft ccw and one to retighten. Mike

LMAO. I suppose that's one way to do if you had 3 hands. There might well be a simpler way tho
Haha

Three,


In all seriousness tho. I myself have adjusted them and had the arm slip ever so slightly out of adjustment while tightening the nut. Also, If you use the throttle lever to set to WOT during the adjustment there is also room for error. I like to do it with the cable disconnected to make sure I am getting it to WOT.

I think you probable have it set correctly tho. I would look into carb and fuel flow. For instance, how long was the carb sitting off the engine during all this. 10% ethanol fuel can gum things up in a very short time. I would take carb off, clean it real good. Set the float. I would also blow out the lines and clean the tank. Make sure the screen in tank is clean or replace and replace fuel filter if you have one or clean sediment bowl. Our Kohlers should run on the rich side. With that said proper fuel flow is crucial.

As a test you could try running it at WOT and start closing the choke to see if it smooths out. If it does then you know its a fuel or carb issue.

A good strong Rubber band is your friend doing a governor adjustment.

If your 129 is stock you should have a petcock on the bottom of the tank and the top part of it that you can’t see that threads into the tank is a wire mesh type filter that may be clogged. Checking/Cleaning everything out fuel related Is a good idea as this may be a fuel starving condition as stated as well as adjusting main jet correctly

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
