I know some of you guys don't have a good meter to set the timing on the front mount distributor so after some thought I came up with this idea:
Instead of looking for a needle to swing or numbers to change you will be looking for a blue light. Just like a spark plug gives you a blue spark (or should in a perfect world). This nice thing is it does not care about polarity so if you connect it wrong it will still work. Clip on end to the distributor body and the other to the flat spring on the points. Move the adjustment screw on the side until the blue light comes on. It gets its power from three AAA batteries. Replacement batteries are easy to come by (just look in your grand kids toys).
I got enough spare parts to make 9 more if somebody wants one let me know.
