    Is the plug wire connected to this unit?.If so you have a magneto which directly supplies the voltage to the plug.If there is a separate unit which is connected to this device and in turn is connected to the plug you have most likely CDI system.I strongly suspect you have a magneto.

    yes the plug is directly conected to this magneto.

    ppl onhere talk about upgradingthe cdi to improve performance, mabyethis isnt the case!

    If your simply trying to relace your CDI for better performance your most likely going to be out of luck....rotary parts seem to be very purpose-made & not interchangeable with anything else.
