Is it turning over and just not firing? I'm guessing it's a fuel problem. Maybe stuck float valves? Try squirting a little gas or starter fluid in the carb opening and see if it fires. That will rule out an electrical problem.
Not sure about the carb'd versions, but on my '05 C90 (fuel injected) the pickup coil on the stator has gone bad twice.
