Engine slow to throttle up
I've got a K321 on my 147 that's hesitant to throttle up. By that I mean when I let it run about 1/4 throttle and hit the linkage on the top of the carb it pauses for a second then throttles up. Is this normal, or could it be getting too much air some how? The shaft going into the carb has some slop (it's 40 years old, and it's worth mentioning that it's a Kohler carb not the walbro one). It runs great when it's running at a consistent speed, it's just slightly hesitant to throttle up when I hit the linkage quickly. Is there a bushing that goes around the shaft that goes into the top of the carb?
I've adjusted the screws on the top of the carb in the past per the manual. PS Happy 4th.

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.
