Fuel cap not allowing air in, eg vacuum locked.
Carb float 'water logged' if cork type or if metal- a hole in it.
Could also be a wire grounding out on ignition low voltage side.

If it idles but won’t accelerate, unscrew the main jet and run a thin brass wire, aluminum wire or a bristle from a brush through the jet to clear any gunk. If worried about damaging the jet during removal just leave it in and carefully clear it.

Assume this is your Cub 2544 with the Kohler 21 twin Cylinder HP Command Engine you are asking about?

All the replies above are "spot on" as it seems to be a fuel issue. My experience and suggestion after rebuilding the CC 18HP Magnum carb, replacing fuel pump, is to get a complete replacement carb setup.

My CC 1811 Kohler magnum became a hard starting engine - rebuilt the carb, installed a new fuel pump still hard to start. Replaced the carb 3 years ago - now it kicks off immediately. very little choke required anymore. IMO with the methanol gas, the seals swell and jets become clogged, so a rebuild kit only solves part of the problem.

To test, remove the air filter housing, put some gas in a spray bottle and spritz the carb, start it, then "spritz" as needed to keep the engine running.

If this works, then either order a new carb or do a carb rebuild.
