How about the fuel consumption on different types of venturis? and their pros and cons?

Generally the smaller the venturi the better the fuel economy, with a corresponding reduction in top end.
I think you find most guys run the 7mm venturi, which gives the best of both worlds.
Really slippery or dusty track, maybe go down to the 6.5 for a smoother application of power.
