wico ignition identification.

[Mark Loraine]

I was wondering if this wico ignition system had any 2-cycle application for kart engines or is it likely to be a 4 cycle set up?  All I know about it is the part number is fw2588b. My time researching it has proved nothing so its mostly likely going to have to be eyeballed for possible identification.
Thank You,
