Orange/yellow gunk from generator cap?
I recently ran my generator for 2 days, pretty much non stop. When I was closing up to head home I noticed that there was a bit of 'gunk', 'sludge' that appeared to be coming from the air vent hole in the fuel cap for the generator. Has anyone experience this? Fuel was not old. Cheap maybe, but wasn't sitting around in the garage for weeks....
