geza: procedure as cited is correct according to bentley, and will yield 5 deg atdc. therefore, lining up u-mark with case center yields 0 deg btdc, and then u-mark before centerline by 5 deg yields desired 5 deg btdc. since u- mark and v-notch are themselves 5 deg apart, it is easy to gauge when u- mark is at 5 deg btdc (and v-notch 10 deg btdc). dan On Sun, 5 Mar 2006 16:43:17 -0500, Geza Polony <gezapolony@SBCGLOBAL.NET> wrote: >Hello Folks, > > >Can anybody explain how to set the ignition advance, in simple terms?
