Default 149/K321 Throttle issue
I replaced the carb on my 149/K321 and I am having some trouble with the throttle after reinstalling.

The throttle lever is moving out of full open on its own. If I hold the the throttle lever in the full open position it seems to be running ok, but as soon as I let go of the lever it slowly creeps towards idle. At first I thought the cable was slipping thru the set screw but I assured its the governor arm pulling the cable on its own.

Im wet behind the ears and need someone to point me the right directly for adjusting this. I did see the instructions for static governor adjustment but I havent tried that yet since it was running fine with the old carb and I thought maybe it was an issue with my linkage ball joint since I had removed it. I also didnt want to throw it further out of wack before asking here.

Thank you for your time,
Mike

I replaced it with a #30 carb, the other was broke.

Whats happening is the throttle is creeping towards idle when the engine is running. My linkage is wrong or my ball joint is not correct. (I removed the ball joint fitting from the rod during removal). I say this because the it was running fine with the old carb. And if I hold the throttle lever in the open position its running fine.

I did the gov. adjustment as per the service manual but it appeared to be ok. The cable/gov still creeps towards idle.

Heres some photos of the linkage in the open position, does anything look wrong?

I tried a few different ways with the springs/sensitivity with no change. I checked the governor arm adjustment. It leaves me with a few things:

Is my cable bad or not attached tightly enough?
Does the balljoint on the end of the rod have to be properly adjusted?
fiunally, can a carb thats not properly adjusted cause the the governor/throttle cable to move?

PS sorry for the long winded posts

Sounds like the throttle lever under/behind the dash needs tightened up some.
That's the first place I'd look.
Does it seem a little too loose and too easy to advance?

Is the cable sheathing attached properly? It should not move.....only the cable wire.

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.
