If the two plugs didn't look the same you may have an issue with the cylinder that the plug was more black. If it has a intake valve issue, that would cause the fuel mixture to be off and jacking with the choke would help. It is possible that is an issue with the carb, but being that it runs fine at WOT but not at idle and that it happened suddenly, I'm betting it's a cylinder issue. You can look into it (the carb) if you want, but I don't think your going to find anything. More than likely your going to pull the head on the side with the black spark plug. On another note, it is possible that it is a spark plug issue. What plugs did you use (Brand and number)?

Check and make sure you have good spark on both sides. If so, do a compression check. There is no compression release on these motors.

Ok so I did go out earlier & attempt to remove the carb but I ran into trouble trying to get the throttle linkage removed from the carb. So I just stayed calm & put it all back together. I did notice a very small gas leak at the fuel line & the fuel pump. I installed new fuel line there. I started the thing up & ran it at half throttle for about 15 minutes. It now runs good at full & half & even does idle but just a bump up from idle the rpms still jump up & down. I can check spark but at this point I have no way to check compression

O'Rileys or Autozone will rent you a compression checker at no charge.

Fuel pump going south? Mine would start to run erratic and when I pulled the choke out it would smooth out.

It's possible.
In this case the plug color not being the same has me wondering...
It is also possible that there are two problems.

common problem with a common repair, why do you need a compression tester for a probable fuel issue ?

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.
