So after 5 long months of work, I finally have the 2056 built and installed. (IMG:style_emoticons/default/piratenanner.gif)
I have a couple questions about the 123 4RV distributor. I haven’t hooked it up to power yet, but from my understanding, you hook up only the red wire and then power the ignition and a light should come on in the body of the distributor. 1) Since our motors go in a CW direction, the first movement of the distributor goes clockwise until the light turns off? Then CCW until the green light comes on? Correct? 2) The engine has dual carb Webber 40’s/Web cam 86a/Mild port and polished stock valve heads. My question is what setting should I use on the distributor? From what I see it looks like curve #3. Does this sound right? 3) Do I use the vacuum port on the distributor body to the base of one of my carbs, or do I plug it off, or do I leave it open? Thanks in advance for any info!

The Bosch coils had it built in so no ballast was necessary. Perhaps your coil does not have that. I don't think it hurts to have it. Others will know more than I.
