782 kt17 with no compression #1 cylinder

I have a new to me Red IH 782 with the kt17 Series 2. It was not running when I got it and won't win any beauty contests but it is very complete and unmolested. With a good cleaning of the points it fired up and runs...However it only runs on cylinder 2.. I have checked things and what I have found is that there is Zero compression in cylinder 1 and about 85psi in #2. I have checked that I don't have a stuck valve and the clearance between the valve and tappet is in spec so it isn't that. I am new to the kt17 twin, so looking for things to check. I am not familiar with the compression release system on the kt17. Could that be the problem before I pull the motor and start tearing into it? Thanks

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.
