ok so im running a flotek dune ported 350 on gas with a stock head, t5's, +4,stock carb, toomey 1-2 filter, at 600 asl, 70ish weather. when i got the cylinders i started at 360 main, 30 pilot, stock needle middle clip it was way rich(20* weather). now im at 320 main(wot chop shows perfect reading now) leanest clip on the needle and 27.5 pilot. my throttle response is as follows 1/8 pulls good, 1/8-1/4 pulls good but feels and sounds lean, 1/4-1/2 puls good maybe a lil lean, 1/2-just under 3/4 to rich, hesitates, loads up if i stay there to long, full is nice and smoth through all rpm. so my next guess is a different needle but what one do i get to achieve my needs?
thanks
