Hey 'Rutan' I never thought of that when I was flying higher performance, 'carby' pistons.
However, if it works for you...I wonder just how much fuel you actually saved?
Care to elaborate?
Half a circuit's worth...or more..?
The only comment I would make is that the use of the Carby Heat delivers unfiltered air - so you wouldn't want to have any 'dust' around....
Cheers
