KOHLER WONT START

I HAVE A CUB CADET WITH A KOHLER 26 HP SV725 COURAGE, IT WONT START UNLESS I SPRAY CARB CLEANER OR SQUIRT GAS IN THE CARB THEN IT WILL START AND RUN FINE.. IF IT SITS AND COOLS DOWN IT WONT START BACK UNLESS I SPRAY IT AGAIN...:confused2:

Make sure the choke is closing all the way. On some mowers that have a common throttle/choke the cable slides in the holder and then the choke doesn't close all the way, preventing from starting.
