RE: $25 CDI
I got my XYZ ignitions the other day and installed one on a 25cc gasser from a Feather lite weed eater.
It was easy to get the timing set, starts easily by hand with great throttle response. I'm pretty happy with it.
Mine were on backorder for about 15 days, I bet they are selling like hotcakes, the stock listing on hobby city's website said -14 at one point.
