I am trying to download the HU Fuel System manual, but 4shared is acting weird and won't let me because I'm not a "premium member." I should've just went ahead and downloaded it with the others, but oh well. I need to know how to adjust the idle speed on my Holley 2 bbl. It is currently running 900-1000 RPM, and I know it should be 650-800 RPM. Maybe I'm just being too anal, but I like for things to be done right the first time, and not have to do it again. Would the extra 100-200 RPM make that big a difference?
