Case 444, Kohler k341 wont stay at WOT for mowing.

Post by RyanD90 »

Hi all,

I am having some issues with my Case 444 with the Kohler K series staying at WOT. If you push the throttle up, it will stay up there for bit bit eventually makes its way down to mid throttle. I have adjusted the throttle cable and it seemed to help a bit but im not sure if the governor springs are in the correct setting. Or is there another avenue I should be checking?
Thanks! :creeper:

Is this new or has always been like this? Possible issues:
* carb screws need adjusting
* not getting enough fuel to the carb, from pump not pumping enough, or crud in the tank
* governor not set right

@RyanD90 This sound like the throttle lever rivet and friction washer is loose. It can be a pain to get to. One solution is replacing the rivet with a bolt and nylon lock nut. Another is mashing the rivet with a visegrips.

I have a 446 that the throttle backs off over a long enough period of time that fixing it has not became a priority yet.

Agreed , I have had to fix the throttle cable on every Case I have done . But when you consider the age of these things , but once fixed seldom ever need to be addressed again.

Agreed, my John Deere has a nut and bolt in the throttle lever, and my MF16 needed the vise grip trick put to it.

You can also just cut a sliver of wood just wide enough to drop into the slot that the lever travels in, and long enough that it wedges the lever all the way into the forward position.

For my 442, the center button was missing out of the steering wheel. So I used the little cup in the center of the steering wheel to keep my wood wedge in.

Low tech, but instant, free, and foolproof.
