Carter BBD carb automatic choke

[brians69d24]

I picked up a carter bbd carb from a '73 Winnie (I didn't pick it personally)  to go on my '69. It has an electric automatic choke (yeah!). Now I know some of the chrysler products with electric chokes had choke controls - essentially a timer. Is this one of them?
  I powered it up and the coil eventually got really hot and it seemed to pull the choke completely off in 3-4 minutes so I'm guessing that it doesn't.

2nd question: There is a vent over the accelerator pump that goes to the evaporative control system...I think that it is those charcoal canisters? I don't have one. Is there somewhere else I can feed that to? I was thinking the air cleaner but that would draw a vacuum on that and I don't think that would be a good idea.
thanks!

They started electric choke in 72.  Sounds like that one is working as designed.  Not sure if you could convert it by using components off the original carb but might be worth a try if you do not want to use electric choke.  Otherwise, just add a set of wires per the 72 or 73 wiring diagram.  They grounded the choke at the alternator.

They started using the Evaporative Control System in January of 1973.  When the engine is not running, gas vapor in the carburator bowl area was routed to and stored in the charcoal canister.  When the engine is started, the stored vapor is recycled into the engine via vacuum.  If not connected it most likely will not affect you unless you have emmissions checks in your state and they like peaking under the hood.

OK, I'll just plug it off then.

Hey Dave,
Where do I tap power for the choke from? I thought I read that you don't want to take it from the coil because it can drop the voltage down too much.

thanks
