Downdraft questions

[pick]

I'm running twin 97s with adjustable jets. Works great. Can be infinitely fine tuned. as far as a "bench mark" setting, just keep written records of how many turns & the results/conditions etc. I keep mine in the tool box for reference. I did really screw the settings up once trying to tweak it for a hill climb. But once it was dialed back in, I haven't changed a thing in nearly two years of all kinds of driving. Must have gotten "the set up" right.....
