i get the fuel consumption .
just keep working at it . But think each circuit and then how it interrelates to the next .
Im not a luddite but carbs work pretty good and will rarely let you down on the side of the road .
oh i probably wouldnt be using a 9.5 power valve .
that is way high ! I run a 6 or 6.5 , factory is 4.5 . But i have a very large converter and hence not much load at cruise but high vacuum . My vacuum @ idle is 4 or something close . With a lower PV say 6 or 5 whatever you will find at cruise you are on the jet but pv is closed and will clean up
