[C320-list] Normal Performance Limits?

[Kirk McCullough]

Brian

The Kiwi prop pitch is easily adjusted with an allen wrench. My "from the 
factory" setup gave me 3000rpm max I did 1/2 turn on each blade and now get 
3300, with my Perkins.

Black smoke is an over loaded engine or perhaps the exhaust elbow is 
partially plugged
