Having run gassies for 15 years I've found a system that seems to work for me and that is : first of all set the needles to the factory recomendations . Then screw in the low speed needle ( the one closest to the engine block ) until the engine won't run , then open an 1/8-1/4 turn, open the throttle and adjust the high speed needle for peak RPM's, then open the high speed around 1/8 turn, you can't burn out an engine running it a bit rich . Adjust for a smooth transition with the low speed by opening it . Two items that help out are an electric starter and a fine screwdriver with a piece of brass tubing on the end that will fit over the needle . The engine must be stopped for adjustments keeping in mind the emergency rooms are full of people that took a shortcut and ended up with a longcut ( on their hands ) . Have fun safely .
