Default 782 with M18 problem

So i put this rebuilt M18 in my 782 and i can't get it to stop hunting. It appears lean and i can't get it to smooth out. i have replaced the carb, fuel pump, fuel line and gaskets. I also took out the fuel tank, valve screen,and cleaned them. It has good flow to the pump

Still no difference, actually worse. idles with the low speed shut and high speed just hunts with the high speed mixture screw out to stop....

Doesn't miss just lean. Pulled plugs and they are dry and clean so they are firing.

What am i missing ?

Now, Did you touch anything on the governor? Move a spring?

You say you replaced the carb.. Normally I would assume that means new carb but you didn't say new. Is it new?

That is an odd issue indeed. Should not run with idle screw shut. And nothing changes as you open it?

Has the governor been adjusted according to the procedure listed in the Kohler manual? If so and it still hunts, it's a mixture issue. If you haven't followed the service manual to adjust the gov, do that first. The only way it could hunt from mixture is if the high speed were nearly closed and extremely lean. Also, have you got a constant flow of clean fuel to the carb?

Another thought, some of us using the chinese carbs have found the float to require adjustment for proper operation. You may need to check that as well.

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.
