While the carb was off I I cranked the engine a couple times and saw gas pump out of the open gas line, which was a good sign.

I have the original carb that the previous owner pulled. I just finished cleaning it up and will install it in a couple days and see if things get any better. The jets on the old carb flow great, I am hoping that this does the trick.
On the china ebay carb... how was the float setting?? A float not set properly could cause both surging and hard starting. Out of the 10 or so china carbs I have purchased, at least half of them needed float adjusted out of the box

I agree with the float setting. I just repaired a 22hp Kohler Command that would not run without 1/3 choke applied and would backfire and die when the choke was removed or the throttle was increased. Gas level in the carb is not high enough due to incorrect float adjustment.

The only adjustment that I could see on that ebay carb was the low speed idle screw. Flotus leaked fine, no debris and it actuated as expected. The only thing I could do on the ebay carb was clean it.

all floats are adjustable on these carbs. "leaked fine" is not the way to check... Think you need to look over a manual.

Ive never purchased an aftermarket for a IH cub that had a plastic float. Granted ive only replaced carbs on older tractors than the OP tractor. Did not know that you could. I guess there are some REAL cheapies out there besides the run of the mill cheap.

If the float in original carb is good.. Do you know if one would work in one of these carbs ?

Correct float is not adjustable on the original or the ebay special. Both are plastic like pictures above

Well, I cleaned the original carb and put it on. Need to work on the mixture, but she runs way better. Rpms seem low right now, I assume mixture adjustment will help there. Also, it starts perfect,which is what I wanted in the first place. Had it out for several hours today doing work outside and it performed will.

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.
