Thanks Bob and Thomas, I will do both.

Today, we replaced the new Bosch transformer with an earlier (black) one from a '78 SC and it certainly made a significant difference - fired right up and I got my "snappiness". My idle went from 850-900 rpms to 1050-1100.

We discovered that the newer one installed was incorrect, it was intended for '65-68 model years...confused on how that got into our BOM for this project but we had been collecting parts over a 2 year span.

I cleaned out the tail pipe - removed all the black soot and snapped some before pictures. We'll finish off this tank and give it a break for the holidays and will reengage in the new year.

Now, we are back to 0...but feeling better about dialing-in the fuel/air ratios, advancing, and a better replacement transformer (I hope one is out there somewhere).

I'll keep this post going, hopefully, someone else will get some benefit out of it.
