Cleaning out idle circuit on Edelbrock AFB

Put it back together. Fire up. Rev the holy piss out of it. While holding mega high rpm, slap something over the carb mouth. You want something that seals well, no air leaks. Couple shop towels, your hand, mother in law's muumuu, whatever. Choke it until it floods out and dies (some guys manually close the choke at the same time)

The suction will pull a surprising amount of crap through. Hold throttle wide open and crank until it clears out enough to restart. Rev it a little and see if your idle has improved.

That's the Italian Tuneup. Works great on Fiats.
