Definitely seems like that's your problem with it not running, big evidence on that piston. Reminds me of the old phrase of throwing the hotdog down a hallway. I'm wondering if that would even seal up at .030" over? Is there a ridge at the top of the cylinder?

Guy's I de-glazed the bore and put in a new .010 over piston and rings.
Still no start. I re-checked compression and still 37 psi. I read that if you spin the motor backwards it disables the acr I wrapped a rope around the pto pulley spinning the motor backwards and it read 110 psi. What could be wrong here. New battery, coil, condenser, points, plug. Point's are static timed to just open when s mark is in middle of sight hole. Re-built carburator and tried a new on also. All new wiring. 12 volts at coil. Won't run on ether. Spark looks good grounded on head. Any more ideas John

No I didn't. I just de-glazed it and re-ringed it. It never smoked or anything.
I would think I could at least get it to start.

Won't matter if you do, it will likely seize within the fist 8 hours.
Did you even check skirt clearance? Did you take the cam or crank out? Is the cam in time?? Before you tore it apart to do the half-assed rebuild, I asked if the spark plug was getting wet with fuel. You never answered. Does it? Since it takes no hit off either, I think your timing is off, or you aren't really getting spark. The engine is obviously wore out. You really should rebuild it correctly.

I agree with Jon you're asking for big trouble fast without properly sizing the bore.
Reading through this whole topic, what about fuel quality? Is it new, fresh gas, or stuff sitting around for years? If you have spark, fuel and compression this thing should do something, (sputter, pop, backfire, etc, anything really) and thusfar it sounds like it hasn't.

haha I knew you guy's were going to say that.
I think it just tired. I never took the crank or cam out. Plug looked like it was getting wet. Didn't really do a rebuild just tried some new rings for fun. I really just need to do a proper rebuild like you guy's say. Only problem I see is somewhere along the lines (it's already .10 over) somebody welded the pto pulley on the front of the crank. If I decide to put a reman 10 or 12 horse in it what parts are interchangeable. Different starter gen bracket, muffler,flywheel and carb obviously. Anything else. This is in a 86 Cub Cadet. Thanks again fellas. John

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.
