CC 129 Hydrostatic/kohler won't start.
I used this tractor daily up to about 6 weeks ago when I started working on my CC 124 where I was installing a creeper gear. It has been in the covered garage since. Went to start it the other day, turned over etc, good fuel but no spark when tested. I looked up former threads and it was suggested that the condenser went out first then the coil. Since my 124 had a new condenser and working coil, I did a switch test today and still no spark. I took off the points cover and watched the timing pin as i turned over the engine and at no point would it open the point gap. I tried adjusting the point gap but no matter how tight I could make it the pin would not open the gap when turning over.
A friend suggests that I remove the pin and compare its length to the one from my CC 124 with the similar 12hp Kohler. If they are both equal length, then am I dealing with a worn timing cam? The previous owner unfortunately painted over all the id plates except on the left rear axle with these numbers visible: 2050046U465(?)5001. The Kohler engine is totally similar in all respects to my CC124 Kohler. I have no further identifiers for this machine.

The points only open once every two revolutions....... You sure you turned it enough times? If the motor was running when you parked it, I highly doubt that it is anything major. Check the points again.

Looks like that Points Assembly is pretty dirty and I see lots of rust.
I would suggest, that you either (A) clean and polish up, or (B) replace with new, the points assembly. Next, where the points assembly mounts to the block, clean and polish that area to when the points are mounted, that they are mounted to clean metal. Check the Ignition Wire to see if it is in good condition and that it is NOT grounding out to either the Points Assembly of the Cover.

J-Mech: Thank you for your reply. I did repeatedly turn over the engine (spark plug removed to lessen resistance) and noted that the push rod to the breaker points barely moved if at all. I then pulled the breaker apart and checked to see if the push rod could be manually pulled out and it moved freely, so it was not stuck inside the engine/cam shaft. I am assuming that the cam shaft has ellipsoid shape to activate the push rod.
I failed to mention in my thread that when using the tractor in the early summer, whenever i turned the ignition off I most often had a tremendous back fire. could that have done damage that i am not aware of? Also, can you tell me what Kohler engine this one is from the information I have provided? Is it a K90, K91 or...I need to order points and a condenser for sure and possibly a push rod. Thank You, all again.

looking at the one pic I can see a bolt on cam cover so it could be a 241,301 321 341 if it has a flat pan it would be a 241, back firing on shut down is raw gas being drawn into the exhaust, gets hot and backfires, whats a 120 hydrostatic?

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.
