Hello again all! Still fighting an overly rich, plug fouling issue. I have rebuilt the carbs,
replaced the fuel pump (non-VRO), checked the primer solenoid, replaced the reeds
and thermostat. All with BRP OE parts BTW. I'm to the point of thinking there's a
problem with the carbs I'm not seeing. Upon inspection of the carbs, the only thing
that looks strange are some cracks or something in the casting around the emulsion
tube, idle tube area. Am I onto something or grasping more straws? Thanks in advance,
Steve
