I'm running in Tucson.. around 75-80F when I'm racing at night.. I know my idle is set where it needs to be and my low end needle is set well, possibly even a little rich as the motor still doesn't have 2 gallons on it.. I'm running the 2057 as I still haven't found a 2013 or big boy yet.. however when I stop running the engine and let it idle, it has a high idle and then drops to where it should idle.. it will continue to idle for a good bit.. does this mean my low speed needle is a tad too lean? I really don't think I can close my idle screw gap anymore.. let me know what you guys think
