Hi Guys,
I have a stock carburettor on a 66 Mustang running a 289. I for the first time attempted to do a choke adjustment to prep for winter in Australia (I live in Perth, Australia - not the coldest winter, kinda like LA). I opened up my carby and had a few surprises:
1. There is no piston.
2. It does not seem to be connected to the throttle at all. Pressing the accelerator on a cold start does not engage the choke.
3. It seems the choke was set on an always open position, the spring wasn't even closing it when cold.
4. The choke doesn't fully close when I try to close it by hand, even with the spring disengaged. I cannot figure out what's blocking it. Doesn't seem to be stuck (I sprayed carby cleaner) rather that something is stopping it from closing fully.
5. My guess is this is an Autolite 2100 but can someone please identify it.
The car still wasn't the worst starting cold, the problem was more obvious when I didn't drive for a week. I wonder what I should be aiming to fix! Below are pictures of the carby in its max closed position as well as the open spring housing with the missing piston.
Thanks guys!
