My intake setup:
OEM carbs with oem f/a with 1 screen removed. Jetting: 75 low, 135 high, 95 gr spring, LT carbon tech reeds + angled spacer.
By the plugs I can say the ski is not lean.
I will close the FCV a bit, and put in the plug tip inside the stinger.
I did read all instructions for everything, know the carb jetting procedure.
What else?
Sounds like not enough pilot. Carbon techs need a larger pilot than most others. We run 80s on our stock 701 stuff w/thw carbon techs. You can have a low speed issue that won't show on plugs.
