I've still got the 0.031 the carb came with, so I'm going to try that first. If I need any other size I will drill them. Already got the blanks, much cheaper.
From what I know the jet affects the whole curve; shifting it up or down. A bigger HSAB affects the shape of the curve; richer at lower flows, leaner at higher flows. Like the graph I posted shows.
Just be careful it doesn't go lean at higher flows with the smaller HSABs. Can't remember where I read it but there's a range where changing a main jet has much more effect than elsewhere.
I still like going smaller on the jets better than going with a bigger bleed even if you take bigger steps with the main jets.
"From what I have tested, that is the range for the HSAB's" Not sure what you mean? AFAIK the HSABs have an effect upto max flow?
