yes that makes sense. i'll try that tomorrow. now that there's better weather where im at i can spend all day after work messing with it ha. would the vacuum return back to normal once its sitting at 3k (as if i were cruising at 3k) or does it stay dropped until you let of the pedal? i feel like i've noticed my vacuum only dropping initially on wot then once the engine catches up with how far the carb is open it comes back up to around 15-20 pounds until i let off. because in that case i think my cruising would suffer due to too much advance (34 mechanical plus whatever my vacuum advance would be)
