I would raise the needle by moving the clip down one position and see if that helps. If the clip is not moveable, then you can put a small washer under the clip to raise the needle. The real problem is trying to jet a CV carb correctly. With the CV carb, the slide is not raised by the throttle cable, but by engine vacuum. So even when you have the pedal WO, most of the time you are still running on the needle, not the main jet. Therefore, you are really never sure when you are running on the main jet.
I bet it will help, because most of the time we are running on the needle unless the engine is winding it out to the max.
