Re: timing issues.

That's the one I first measured (the one marked 30). I found that that one measured 9.78 mm with the digital micrometer, but turned out to move .382" (9.7028 mm) using the dial gauge. That's what brought me to figure that .127" should equal 10 degrees. I set a vac can to .127" and installed it in my dizzy, and checked with the timing light. It was bang-on 10 degrees vacuum advance.
