I am guessing when you gun it, it is so rich that it just bogs until the slide is open far enough to cope with the extra fuel and then it just takes off.
With a short LSN screwed that far out it is possibly not even in the spray bar at idle or low revs.
Try setting the LSN at 1.5 in from flush. This should get you running, then lean it in from there until you get a satisfactory bottom end and take off. Then fine tune the HSN a little for peak performance.
Grizz, that's what is weird about this. It does idle, it does not stutter or hesitate from idle like it's too rich on bottom. It's like there is literally a gap between idle and WOT. Imagine this, it's at idle, you move the trigger, the slide opens but it's still at idle, more trigger, still at idle, then you hit 3/4 to full throttle and then BAM, 40,000 rpm. It's very strange. I have sealed the back plate, Carb, New front Bearing, both sides of the carb pinch screw. Stock carb settings are flush LSN and 1 out on top or not? Thanks.
