Hi Dan,

After trying an aftermarket 318 BBD carb from China and facing the same idle stability issue (+new issue of flooding), I looked on the forum and found a guide to distributor rebuilding.
It then pointed me to a service gear needing pin hole adjustment when replacing to cancel excessive play on the drive shaft - I remember I didn’t do that procedure.
Rather than drilling new holes in the service gear, I simply have put back the original gear as it was in good shape. The idle issued has gone
Now I have a spare Chinese BBD, maybe I will reuse some parts of it later to pimp my remanufactured Rockauto BBD (any articles/thoughts on mixing a 318 BBD with a /6 BBD?) .

On this note thank you again for your and others assistance

Does anyone has any pictures or diagrams how factory air intake flex hose should be routed and where connected from the air box on a super six option in an A-body in the 70's? Specifically in '73 Dart Sport models?

This seems to be the last element I have missing in my 198 to 225 super six conversion. Thanks!

Attached are pictures of my current engine bay without the hose.

The A-Body never had a Super Six option, so there is no provision for the air hose off the air cleaner. On the F-bodies, the inlet was between the battery and the radiator, where it attached to a plastic pipe that had its inlet opening down by the bumper.

The Super Six air cleaner is nothing more then a 318 air cleaner with a fancy decal. You could always substitute the base from a early '70s 318 air cleaner to get a more period correct look.

Nice looking engine compartment.
