Won't start after use
MY 1864 starts and mows just fine for however long I need it. If I shut it off and try to start it 10 mins later it won't start.
It turns over and acts like it's flooded, over and over then finally it attempts to start acting like it's flooded and eventually starts after burning off the excess fuel. What would cause the carb to flood when it's shut off? The carb float?, the needle that allows fuel to enter? I'm thinking it must be something to do with the carb. Thanks for any help.

are you sure its fuel related and not ignition? a ignition coil can cause issues when hot,as well as the carb. has the carb ever been rebuilt? is the fuel filter clean? fuel hoses replaced before? . you could try to crimp off the fuel hose going from the pump to carb after shutting it off,that would eliminate fuel pressure from pump being forced past the needle and seat. if that solves the issue,i would rebuild the carb,this new gas loves to eat rubber parts

Thanks for your reply.
Yes, June 2014 new fuel filter and rubber lines and recently new plugs and air filters. The carb hasn't been touched. This not starting problem has steadily gotten worse. Maybe that would indicate ignition coils.

Does it "diesel" when you shut it down when it is hot?

it could be fuel boiling in the carb if the engine is running hot. flooding can be caused by either carb or ignition.

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.
