RE: Are All Rcxl CDI units the same?
More on timing lights!
According to Ignitionman the only rollback lights that work with modern ignition systems are the high end digitals like Snap-On, or MAC. He said the others, (dial type),will be off by 4 or 5 degrees when you are at full advance.
I used a friends Snap-On digital a couple of weeks ago. See link below for an example. Got to say it was REAL easy to determine when your advance is coming in. It has two digital windows side-by-side, one reads rpm and other reads the advance you have it set at. I wanted to see what my advance was at 2000,2200 2400,2800,3000,and 3200 RPM. This thing made it dirt simple. I just went to my desired rpm and clicked the advance/retard button until the timing mark flashed on ZERO degrees. Then you look to see how many degrees you have the light advanced. Easy, and dead-on accurate.
Yes, you can do the same thing with a degree tape or a degreed damper, but you might need two people to be able to watch the tach and damper at the same ti
