Thats a good idea, and I will probably try to do that once I get a few more things sorted out. What prompted this post was that I noticed the difference in power from when I was driving it with open headers to once I was running a full exhaust and was wondering if some intake or carb changes might gain some of it back. The engine seems to like more timing. I started out with 34 degrees (16 initial and 18 mechanical), and now I am up to 38 degrees (25 initial and 13 mechanical) and it is running a lot better.
