So I picked up a second hand Weber DCOE tuned for a pumped 1380, so my relatively stock 1275 will need less fuel than its probably tuned for. After reading a number of articles online, and feeling most of the info is over my head, I am looking for advice. Now, I don't really know much about my 1275. It sounds like it has a slightly lumpy cam, has a crappy header, thats about all I know. So with that, what might be a good starting point for selection of idle jets, emulsion tubes, venturi, main jet, etc. I am just looking for a starting base line, then I can go from there.
