Thanks 2 new carbs mean more $$, but it was too cool to pass up. I'll look into the AVS2 @j par had a dq setup also, hopefully they will both chime in.
I got a pair of 500 AVS2's for my setup. (Just the regular ones, not the "calibrated for dual quad use" ones) Hopefully @318willrun will weigh in, I think he has a dual quad setup on a Duster.
