FH661V-AS05-R. On a Cub Cadet RZT50. Picked it up last week. Ran but wasnt running right. Pulled engine cover, found typical nest, and found the left plug wire was eaten in half. Ordered new coil, plugs, and all the basic tune up stuff. Started it and runs great. BUT there is no throttle response at all. The previous owner said he had been mowing with the choke on partially because it wasnt running right. So I dont know if he made and adjustments on Gov or carb to compensate for anything or not. Here is a short video of running the throttle cable lever from fast to slow. And some pics.

Ok. So I adjusted the gov and now have throttle response. It just seems like its revving at a high rpm when throttled lever is up all the way. Maybe it's just me? The machine bounces real easy when driving on my lawn at full throttle. Seems like something isn't quite right yet.
 
The plastic governor gives this engine fits as it will break the little knobs off the governor and run good one time and not the time
