Was using my troy bilt rider when idle dropped a notch or two even though throttle was still up to highest idle(rabbit). It's a 2006 23.5 hp. What could be the problem? Changed air filter,gas filter used carb cleaner on carb,added a little fuel system cleaner to gas,checked fuel line for debris and found none.
