After fixing my no spark issue I have come into an issue with my bike not holding an idle. I recently rebuilt the carbs with new kits, adjusted the floats to the proper 21mm. I can get the bike to start by holding the throttle open but once I let off the throttle it just dies, every time. I have adjusted the mixture and throttle stop screws, Throttle stop: 1.5 turns, 2 turns, 3 turns out, all the way in. Nothing is making a change, the slides are in properly with reapect to each side. It slowly revs up to 3k rpm amd stays there, once I even thinknof letting off the throttle the bike just dies. Any ideas?
