Hi guys,
I have a 1966 Mustang Sprint 200 6cyl auto with a Autolight 1100 carburetor.

I set the timing and it helped it start and run much better.

The car starts and runs good when it is cold and the choke is closed.

As the engine runs and the choke starts to open the engine dies before the choke is open all the way.

I adjusted the screw at the base of the carburetor; that didn't make any difference.

What now?
