Choke control assembly w/knob (shown in photo's above!
*** THIS ITEM IS BEYOND RARE - NONE ON EBAY NONE ON INTERNET (THAT I COULD FIND)
IN INTERNET FORUMS-
PEOPLE THOUGHT THAT IT WAS AN EARLY FORM OF CRUISE CONTROL!
I USED TO USE IT TO WARM UP THE ENGINE ON COLD MORNINGS- MINE HAD A THROTTLE - BUT YOU HAD TO PULL IT OUT AND HOLD IT!
MUCH MORE CONVENIENT, JUST PULL IT OUT AND WAIT TILL ENGINE IS WARM!
