Default CH20 Idle speed

I have a CH20 in my 782 that the idle speed changes about 200 rpm from cold to warm. If I adjust the idle speed to 1200 when cool, when it warms up it will be 1400 rpm at idle. So I set it warm and keep from pushing the throttle all the way down till it is warmed up. Has anyone else had this happen?

Never put a tach on one but they all seem to pick up RPM's once warmed up. I wouldn't worry about it.

I am using 10w-30 oil and I just thought it was unusual. By cold, I am talking 70 - 75 degrees. Just can't remember seeing an engine do that before.

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.
