rolland, do you know the factory setting for the low speed screw on the carb?
low needle flush
high needle 3.5 - 4 turns out
idle screw set so the opening is about 1mm
Also, be sure to check that the nipple on the tuned pipe where the pressure line attaches is clear of obstructions. Seems like a bunch of the latest batch of Genesis trucks have too much thread sealant on this fitting and it goops up the inside preventing the exhaust from properly pressurizing the tank...
