Re: Stutter in acceleration
I too am not acquaited with your carb ..... but......it sure sounds like the accellerator pump... since it's a lean condition....but you're sure that this is in working order. BTW how is the accell pump actuated on that carb?......external rod?.....adjustable....maybe a longer stroke....bigger squirt??. Just for speculation have you tried playing with the timing.....maybe. You obviously have something wrong in the idle/transitional circuit of the carb ...... does your carb have the little vertical slots that span the bore just above to just below the throttle plate.(these are for that "transition")..and how's your throttle bore alignment? Have you played with the timing just to see the effect?
Where's dorfs when you need him?
