Peter - sold out of the carb you need, so the posts were strictly advice only, no axe grinding.

Go to your local auto parts store with the tag number on your carb, and acquire a rebuilding kit (or, if you would rather, call).

If you do not have a service manual for your car, get one! It will be handy for many other procedures. Part of the joy of owning an older vehicle is learning about it and solving issues. Read the section on rebuilding the Rochester before you disassemble the carb. If you have any questions, ask them here.

YOU CAN rebuild your carburetor!

Why spend the extra money to acquire another?

As far as the auto choke is concerned; call (normal telephone hours please) and I will be glad to explain its function, and what to do to make it work. The original choke will function far superior to an electric. Understanding is the key.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
