Jon-
The carbs are numbered 2101S.
When time allows, I'll dig into the front carb to make sure everything is as it should be. It seems like it worked when I used it as a single.
The multiple spring advice came from a fellow Chevy owner, although he had wide and varied taste in cars, especially European.
BTW, I'm located in Rolla. I bought a pair of your kits when I did the dual setup. Don't you remember? ;-)
