Hi everyone!
I found a pretty good deal (or what I thought was a good deal) on an early Aisan 2-barrel to replace the rochester that came on my 40 from the previous owner. I was cleaning it up and soon realized that it isn't ported for vacuum advance. and after some reading on the forms, it seems that nobody does that for these early 2 barrels. I saw what looked like might be a suitable existing vacuum circuit that I could maybe use as it does not really seem to do much. I have attached some pictures of the carb and what I am talking about below, maybe I could pop out the small metal "rivet" and replace it with a port for the vacuum advance? I have seen something similar on some of the old crowns which seem to have a similar carb.
