Carburetor Info

Check the carb settings, make sure you're not running it too lean under a load.
Kohlers always like to run a little on the rich side, especially if tuned with no load.

Warm it up, tune it, then verify the settings with the deck running
(WATCH YOUR TOES - LOCK THE BRAKE DOWN).
Lean (CW) until is cuts out, rich (CCW) until it loads up, 1/2 way between,
then about a 1/4 turn back to the rich side (CCW). And then recheck idle settings.

Too lean of a carb means a hot runner.
