It will need bored. Doing a rebuild without boring is a waste of time and money. If it doesn't need bored, it doesn't need rebuilt.

I've bored several of those 7's to the large bore. You can even put the 8hp crank in them if the short stroke crank is bad, however, it is important to note that (at least some) of the 7hp motors don't have the notches in the bottom of the cylinder for the longer crank. You have to make the notches for it all to clear. Also, pay attention to the cam. When going to the longer stroke crank, make sure the cam is notched also or the rod will hit it.

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.
