Default LTX1050 Kohler 22hp starter can't overcome compression and stops rotating

2009 LTX1050 22hp Kohler.

The starter tries to rotate the engine but stops on one cylinder's compression stroke. The engine also seems very hard to turn past this point by hand.

Turning past the hang point by hand and engaging the choke seems to help it a bit, but on one of the cylinder's compression strokes it will still try to stop even after the engine gets some rotational momentum. The closest thing I can think of that seems similar to my symptoms is "hydro-lock"

The battery is 5 days old, the charging system is working and it looks like the starter itself is new. All electrical connections have been cleaned, connectors removed and contacts cleaned well, battery connections checked and contact cleaner spray for electronics has been worked in to the ignition switch. This was the reason I took the gas tank out, so I could get to the connectors and get the stuff out of the dash to work it all over.

Are there any known pattern failures that match these symptoms, or maybe someone has a diagnostic chart?

Thanks

I am reading on the net about several people having this same issue. Am I seeing it right there is a gear driven compression release of some kind on this engine?

Also is this 22hp Kohler known for valve train issues like backed out rocker studs, rocker arm, bent push rods or stuck valves?

I can see any of these causing the symptoms.

Was it doing this before you had fuel tank out? We need some back history on this tractor. Start with the last time you heard it run please

1. Determine which cylinder is causing the issue.
2. Remove valve cover on that cylinder.
3. Inspect rocker arms and push rods.

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.
