    I have a JD mower with a Kohler CV15 engine. It runs fine for a while, but once it heats up, it starts missing and blows black smoke. The plug is carbon-fouled. I replaced the float needle in the carb and readjusted the low idle needle to no effect. I didn't pull the welch plug (didn't have to tool to reset the new one), but I soaked it in cleaner and blew everything out.

    Is there anywhere that I should be looking other than the carb? Could it be weak ignition? Any other ideas?

    I would say probably weak ignition module. Not a huge issue for Kohler but it is seen every once in a while.
