Default 1872 losing power

the 1872 has recently been acting up. it will run great for about an hour and then its starts losing power when it gets a load. (hills, tall grass) ill have to choke it out to keep it running. ill stop for a minute let it idle and then its ok for another few minutes. it seems to be ok on flat ground. what i have done so far is check the plugs (good shape) checked fuel flow (good) new fuel filter. my next guess would be the carb float might be sticking? what do you guys think?

I think you are on the right track, sounds like a carb problem.

Is the fuel tank venting? Loosen the cap and see if it runs ok then.

sounds like it might also be getting hot... wich would make sense that you have to choke it could be boiling fuel in carb just my

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.
