Gov/RPM set: am I doing something wrong?
After the recent motor swap on my Super, I wanted to make sure the motor was running top notch as it sounded too "tame" (didn't sound like it was running at the rpm it should be and seemed to be bogging down too low under high load when mowing tall grass). So I ordered a digital RPM gauge online and had a bit of time to play tonight. Starting off, the idle RPM was around 1000 rpm so I upped that to about 1300-1400rpm. All good there (based on the Kohler manual, of course). Then I set to work on the high idle. Butterfly wide open and I was getting about 1400 rpm or so at idle. So I, just to be safe, reset the gov as it should be (full counter-clockwise) and then adjusted the high idle screw. I tried half a turn, then a full turn, then two turns, and all I was able to achieve was upping it to about 3500+/- 50rpm. Seems like the adjustment should have had more effect than that as it hadn't changed much from when I started, no? Seemed like no adjustment I made changed it from the baseline of about 3450rpm very much. As time grew later, I had to quit as the neighbors had kids and I'm sure they wanted to sleep over the roar of the Super
 So, am I missing anything here guys? I had thought that no load the high rpm should be around 3600-3700rpm based on the Kohler service manual. Should I keep going or count my blessings and call it good? This rpm gauge, while it seems like it's working alright, it relatively untested. Thoughts on this? Opinions? Thanks guys

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.
