Here are pics of the spark set up I put together for a CMB 101. I never actually tried it, but I have alwasy wondered how it would compare to glow igniton using nitro/methanol fuel. This CDI ignition requires 4.8 volts to operate. You press a magnet into the flywheel and set the wheel magnet so that the system fires at TDC. Then you use the potentiometer on the circuit board to advance the timing. There are other CDI systems that work with a fixed advance and then retard timing electronically as a function of RPM (the lower the RPM the more they retard timing). It seems to me that one would need a dyno to figure out where to set the timing for a given fuel, pipe and engine set up. Has anyone tried one of these systems in a nitro racing engine?
