Hi, guys,
Need some input/advice from the Cub Cadet gurus if possible, please.
I have a 782, KT17 Series I, and I cannot get the engine speed regulated on it. It requires about half-choke to start, but after a few minutes of run time you can push the choke in without creating issues. When you first start it up and it steadies out, it is running at what sound like maybe half-throttle or a little less, with the throttle set at wide-open. Over about 5 or 6 minutes it will gradually increase, never getting quite up to what wide open should be, but enough so that you can engage the PTO and start mowing. After it warms up some more, and about a lap into mowing, the engine will suddenly start speeding up until it overspeeds. If you adjust the throttle downward any at all, it will drop to just above idle and almost stall. You can gently bump the throttle up and it will slowly increase speed again, but will build up again and then overspeed. I can't get it regulated to save my life. I have cleaned and adjusted the carburetor, set the throttle stop (according to the manual, this is the way you regulate the speed on these engines), and even attempted to adjust the governor, which apparently does not adjust the same way the singles do. I'm pretty frustrated at this point - any recommendations, other than driving it off a high bluff?
