Idling way to high

I’ve tried adjusting the throttle cable, even took the throttle off the carb to make sure the slide sits all the way down and nothing changed. Engine gets hot very fast and the exhaust was glowing red at one point. Not sure what to do? Any ideas?

Two questions, what’s the rpm of this high idle and are your valves adjusted correctly? I was concerned about that glowing red exhaust.

I was thinking about lookin in to the valves, but that's way out of my league. as far as the RPM there is no tach so idk the exact RPM
