608KEB 796 #1 Posted November 20, 2012 The throttle on my K241 has been replaced. It has full range movement. Any small increase in the throttle results in the engine rpm's going up to far. it seems like the governor is too sensitive to a slight increase or decrease in throttle adjustment. I mowed the lawn with it this past summer and noticed that maintaining a constant RPM was difficult. It was either to much or to little.I do have a Kohler Sevice Manual and Looked through it. I set my Throttle linkage to 2 7/8 inches. I Adjusted the spring on the (speed control bracket) and the (Governor arm bracket) in different combinations with no luck . Any slight increase/decrease in the throttle over does it. Looking for ideas on how to maintain steady RPM's and more range in the throttle. Share this post Link to post Share on other sites
608KEB 796 #2 Posted November 20, 2012 I was going to try to adjust linkage arm in or out. I don't know if this would help. The spring looks like the correct one, I was wondering if that the problem. Share this post Link to post Share on other sites
rmaynard 16,349 #3 Posted November 20, 2012 Post a picture of how you have the throttle cable hooked up. Remember, the cable does not hook to the carburetor, it hooks to the lever mounted on the blower cover. That lever is connected to the governor assembly which in turn connects to the carburetor. I can post pictures later if you need them. Share this post Link to post Share on other sites
MaineDad 87 #4 Posted November 21, 2012 Do you have the throttle stop adjusted correctly? If it is not adjusted or is missing, your rpms will go wild. Share this post Link to post Share on other sites
TT-(Moderator) 1,162 #5 Posted November 21, 2012 I set my Throttle linkage to 2 7/8 inches. Did you 'synchronize' the governor lever too? I believe it's listed as "initial set-up" in the Kohler manual. Have you actually verified the operation of the governor itself? Start the engine open the throttle by pulling the governor lever lightly with your finger. If you can feel the governor trying to close the throttle, it's probably fine. If the lever moves freely, the tab on the governor cross-shaft (internal) could be broke off or the centrifugal weights may have broken out of the governor gear ~ which means there is no longer a functioning governor.

608KEB 796 #6 Posted November 21, 2012 I think the governor is o.k. It does close the throttle. When I make a change in the throttle It is over-reacting. The throttle seems to sensitive to any change I make. Increasing/decreasing the lever. it's not crazy...but enough to annoy me over time. Share this post Link to post Share on other sites
1973WheelHorse 4 #7 Posted November 28, 2012 Hello, on my wheel horse, there is a screw you can adjust on the top of the carb. :sci-fi-grayalien: :sci-fi-grayalien: Share this post Link to post Share on other sites
MaineDad 87 #8 Posted November 28, 2012 In the first picture, the throttle stop is set way too low. It should be at about 1 O'Clock and it looks like it's at 3 or 4. Do you see that? Share this post Link to post Share on other sites

I see it. It's definitely not in the 'normal' position. @608KEB: Did you use an OEM throttle control as the replacement part? Share this post Link to post Share on other sites
rmaynard 16,349 #10 Posted November 28, 2012 In the last picture, the spring appears to be set in the third hole up from the bottom. Which hole is the other end of the spring attached to on the upright governor arm? On my two B-100's, the spring is attached at the the third hole up from the bottom on both. My guess would be that the governor arm is loose on the cross shaft, or the cross shaft to governor arm adjustment is incorrect. Share this post Link to post Share on other sites
