    Is there some way to do it without a vaccuum gauge? Also, will it help my surging at idle problem? /forums/images/graemlins/1zhelp.gif

    What year vehicle, and what type of carb? (assuming it is carb of course)

    Typically when I didn't have a vacuum gauge, I'd screw them in until they seat, then back off 3 turns. Start it, and adjust until idle was correct.

    Do one side at a time, basically in until the engine starts to stumble, back off a hair, then do the other side. Repeat until you've got them in as far as they can go, with the engine still idling smoothly. (in a nutshell)
