The timing is controlled by the key in the top of the crankshaft locating the flywheel. If this is sheared the engine will either run rough, backfire, pop or not run depending on how badly the timing is out.

Need help with KOHLER COMMAND 15.5 hp (model no.cv15s)

Are you sure the anti fire solinod in the bottom of the float bowl is working as this will shut the fuel off to the main jet, remove it, now switch the ignition on, the needle should retract fully into the housing, failing that there has to be some dirt in the jets, perhaps you could get the carb sonic cleaned this should help to unclog any jet orafices

Kohler command cv15s starter sping in the opposite direction???

It's more likely you hooked the battery up backwards. That reverses the polarity and will make the starter spin backwards.
