C clip in middle is proper position from the factory.
Have you tried adjusting the idle air screw?
Warm up the engine and turn it 1/8 to 1/4 turn at a time until you achieve your max RPM. That's usually the sweet spot. (more than 2 turns OUT usually requires a larger pilot jet, and all the way IN means a smaller Pilot jet is needed)
