Carter Thermoquads ~ 'More General Information'

- Marvin - said

I wrote it yet a few pages before:

I have a 6394S Thermoquad, this number is not listed above, but should be standard on 1972 340s AT for export.

I can - if wanted - post pictures of this special type of Thermoquad, but I cannot tell anything about the specialities of this carb or the differences to the 6139S type.

Note > These 'export' Thermoquad's were designed to run 'lean' in the
Mid-Range level, but to run on the 'rich side' under heavy-throttle.
