Hi All

I'd like to know if anyone has converted a 1956 Teapot carb to an electric choke, and if so, how was it accomplished? Maybe a conversion kit was offered at one time?

Thanks so much

Jim

I converted a 1956 2V carb to electric.  I believe the automatic choke mechanism is the same on the 2V and T pot.  The spring of the electric choke had the wrong rotation for the Holley.  Changed the spring and it works very well on the bench. 

I took an autolite spring, reversed it in the electric housing, and reformed the hooked part that engages with the piston lever assembly.  The reforming is risky, as the spring end can break.  And it cannot be heated to ease the forming.  It would be a good idea to have a backup in case.

Thanks for the info. Can you tell me where and/or what parts you used and what were they from?

Thanks

I bought the electric choke from an outfit in Chicago, think it is Chicago Carburetors, but will post more specific info tomorrow.  The spring used was from any Autolite hot air choke. 

The cap for hot air inlet was a standard fitting used on Autolite and Holley chokes, with the end soldered closed.  But make sure it is the correct thread, as it isnt available at the hardware store.  I blocked the same inlet on a 4100 yesterday, by simply cutting a round piece of cork and putting it in the bottom of the brass fitting, then tightening the fitting.

  Removing the spring from the electric choke is slightly tricky, as it is wedged into the center metal piece tightly.  It was distorted a little during the process, probably could have been put to use again, but went with a nice clean spring instead.

You end up with one minor inconvenience.  The "Lean" adjustment is now in the opposite direction of the arrow.  Choke linkage adjustments remain unchanged.

Thank you so much. I look forward to any additional info you can provide.

I think I can put up with that little bit of inconvenience, re the "lean" direction.

Thanks again
