I realize engine vacuum drops off at the hit of the throttle but does it return in any amount during the run. Just curious. Thanks.

No evac. Just wondering if metering rod springs that were too light could cause the carbs to go lean on top by the vacuum possibly sucking the rods back down even slightly.

Carb setup on mine is .113 pri. .107 sec, .071x.047 rods. orange springs .043 shooters middle or top hole on the lever. Floats set by the book 7/16 drop, .110 n&s. 6lb.fp. Sometimes increase the sec. jet to .110 Runs pretty nice this way. Plan on trying smaller shooters .035 this season and also would like to try different secondary boosters from a set of older afb's (3721 afb from 327 chevy 300hp)just to see how it will work. Anyone been down this road? Thanks for the replys. Steve
