Hello to you all.

I have been given this Zongshen ZS250GS not running. Compression is ok but I have no spark.

I've been reading these thing are notorious for having ignition problems and in most cases the cdi but I wanted to try and rule out electrical before I started throwing parts at it.

So here is my question, should the cdi have 12v at any of the wires? There is currently no power at any of the wires on the cdi.

How do I know if the cdi is the a.c. or dc model?
Should there be power to the coil wire?

Thank you.
