hey guys im trying to get these carbs going right but im having a few problems. im also not to familiar with anything other than cv type carbs. 1st issue is idle. when we start the bike cold , the idle races without any choke and without blipping the throttle. i thought that the slides were sticking but im not giving it any throttle so the slides shouldnt be opening. as the bike warms the idle drops a bit. without giving the bike throttle or ckoke why would the idle race? 2nd question is how does the idle thumb screws work. how do i raise and lower the idle? it does not seem to effect the idle when turing in or out. 3rd issue is the air screw. so this is an air screw? not a fuel mixture screw? does backing the screw out give more air? or turning the screw in restrict air? thanks in advance!!!!!
