Default Piston protrusion K161
Well I finally started to rebuild the 70. Went on eBay and bought a overhaul kit for the k161. Tore it down cleaned and honed it. Put it back together (mostly) because I believe I have a k181 rod instead of a k161. So the piston is sticking out of the block at TDC. Just looking for confirmation. Your collective wealth of knowledge is needed.

I've never seen a piston stick out of the block on any Kohler I've ever worked on. I would suspect something is wrong. Most Kohler heads are flat where the piston is so if the piston sticks out of the block it will probably hit the head. How much is it sticking out?

You have the wrong connecting rod. 8hp rods are shorter. About 1/8 approximately.

It's about 1/8 of an inch so I probably need the 8hp rod. The engine was rebuilt before.

Thanks for the input, I guess it would have been a good idea to compare the two rods before I started.

No need to take it apart, just hit the top of it with the chain saw, then polish it up with the snag grinder.
Being soft aluminum, it will cut pretty easy

I was going to suggest a block of wood and some sandpaper but your way works too.

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.
