this is on my cvk40 swap. i have the idle set at 1500 rpm on my vapor's tach. runs great everywhere, the only minor issues i have right now are; when closing the throttle from cruise, 5k+ rpm, the rpm drops below the idle for a split second, almost like a mini stall, then levels out at 1500. when idling and quickly blipping the throttle, 1 in 4 blips will kill it. neither one of these bothers me much but if its a simple adjustment of sorts i'm game. if its just part of the cv carb, oh well.
