I have an RB C6BBT7 (awesome engine!). How do I tune with the venturi carb inserts? I have the 7,8,9 mm inserts.
Smaller inserts = more runtime right, but how does this affect power. I read somewhere that a smaller venturi=more low end power and a larger = more top end power. Is this correct?

You tune your engine with the carburetor inserts(venturies) in the same way as you do normally. And yes the smaller the venturi the less overall power, however it is indeed true that when you use a smaller venturi you gain a little more lowend rpm power.
