[QUOTE="davidd, post: 25444, member: 1177"] Howard, That is a very interesting result. Like Timetraveler I am interested in your final decision. It seems a bit counter intuitive to advance the timing that significantly. It leads one to believe that the charge, with the addition of the quicker burning twin plug ignition, is burning much slower,thus, requiring more advance. Two things that I think are important with ignition mods: Check the timing with a strobe at least once to verify your settings, and set the timing at least once with a dyno to find out what setting makes the best power. Timetraveler reported Roy Robertson's timing range for his much modified twin to be 18-24 degrees. I have run 19 degrees on my racer for the past five races. I strobed mine and set it on a dyno and I suspect Roy did also. David [/QUOTE]
