    Anyone know what this knob is for?

    Hey Folks - My 1950 CJ-3A has this nifty extra knob on the dash. It's not the throttle and not the choke, those are there. It appears to be connected to a spring wrapped cable that ports into the side of the Engine Head. Is it some sort of second choke or a maybe something to do with cooling...
