Jet sizing question

C'mon guys, you know better!

Your cruising at 2000rpm, your firmly in the idle transition circuit. You need to get the idle fuel restriction sizes and air bleeds in check. SUPER common tuning issue with Holley. Main jet sizes won't do dick. At that speed you can run the car without them!

Invest in a cheap electric drill, and a 1-60 drill bit set. Some 6-32, 8-32 and 10-32 brass set screws AND same sized closed-end hole taps from mc-master carr, and a 61-80 drill bit + pin vice combo from Amazon. MUCH cheaper than shooting blanks at pre-made Holley bleeds n feeds... PM me and I can give you a hand with it, or sift through 20 some pages and draw a your own conclusion. Depends on what your in the mood for... :D
