| Hi Wilf
Carb I have is the 1407 750CFM version. Engine is a 350 chevy with Edelbrock RPM heads and cam.
At the moment I am at number 9 on the calibration chart which is one step richer in the cruise than stock.
I tried number 10 but, although it drove quite well it was down on power and sooted the plugs.
I am currently on the strongest (silver or natural) step up springs.
My next move was to go back to the stock needle rod but keep the stronger springs.
Maybe I should go to 19 on the chart and back to the stock springs?
Craig.
