I have a edelbrock 1406 I need to set the metering screws. I've done holleys but not a edelbrock. Cranking the 2 screws at the front of the carb how many turns backing it off do i start at 1&1/2 or five and a half. I've been told both. It is running very rich I need to lean it out. Thanks. Also my truck is almost ready for the big reveal. Its been a year and a half of sweet and money but it is looking excellent

A great starting point would be 11/2 turns out from bottom. Don,t tighten thrm doen hard when ginding bottom. You shouldn't be far off at that.

If you have a vacum gauge, plug it into the carb base or manifold so you can read manifold vacum and adjust the screws as necessary until you obtain the highest vacum reading possible.
