That seems very plausible. In my particular case, the harness isn't marked. I'm going to replace my mags soon, and I'll install the new ones per the O300 book.blueldr wrote:On those airplanes that had the ignition harness firing "half and half", I would strongly suspect that someone installed a harness designed for one of the larger Continental engines. such as the O-470. New harnesses generally have each wire marked for the proper plug position. Harnesses for the C-145/O-300 are marked differently than those for the big bore engines. Since either size engine may use the same mags, It's possible someone installed the wrong harnesses.
Thanks!
