Sooo my truck will not idle. Under throttle it does fine and motor is solid sounding. It sounds like it misfires a little at low idle then just shuts off. I've checked my vacuum lines and all looks well there. It was really random. Drove home next day won't idle. Any ideas? I'm thinking it has something to do with the carb but I'm not 100% so any ideas would be great. i adjusted the idle screw and it seemed to idle fine then started driving came up to a light and started idling at 3k rpm. I readjusted it and it sorta idles at 1500 only when the clutch is in. When the clutch is disengaged it won't idle. It tries and then just dies.
