K181 governor

I have a model 71 with a K181 engine that I rebuilt last year. The engine runs great, but I'm not happy with the governor action. It just seems wimpy in comparison to other engines that I have done, K301 and K321. My symptoms are that the engine will run up to 3800rpm and then when any kind of load is put on it will drop 1000rpm at least. I don't have a pto on this tractor so the only way to load the engine is to pull something and then it is hard to see what the throttle is doing.

I have adjusted by the book numerous times with varied results. I've replaced the governor spring also. I know this style of governor is different from the bigger engines and I'm not a fan.

I was just wondering if this is a normal thing and I will just have to live with it or is there something else to look at.

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.
