1974 Valiant Scamp, timing retarding when revved
We are on the same page now, I get ya! The transfer slot, or how much of it is exposed on the underside of the blades.
I pulled the carb when I got a break from the rain and set it at .030 using a feeler gauge. This is the timed vacuum port side, as you said it's not exposed at all when the transfer port is spec'd to about .030.
Manifold vacuum port side for reference.
And here is the shot of the distributor, #1 is the wire under the brown wiper wire. Basically pointing to #1 cylinder.
