I have been restoring cars for over 25 years and I can not figure this one out.
I just put a new Holley 350 carb on my 65 Mustang, no problem. what I can not figure is how does the electric choke's Bob weight return to the set cold position. The weight is not attached to anything, proper operation is for it to be loose and free moving. I understand how as the choke heats up, the bi metal unwinds, thus moving the butterfly rod to the open position. at the same time the high speed idle set screw slips off of the Bob weight's notched steps allowing the idle to slow down. But how does the bob weight re position itself to the cold position under the adjustment screw. Is there a spring missing that lifts the weight back up. I might be old school, but this one has me stumped..
Thanks
Woody
