more bad parts

More go kart work today....found more parts to replace - definitely the spark plug, the petcock (not Carl), and the starter solenoid.  While I'm at it - yes, going to clean the carburetor.  Just as I was about to remove it, I discovered it had a coolant line attached to it.  Need to dig through my parts bags and see if I have what I need to clamp it off of bypass it without draining the whole system since I just filled it up again.  86,100,67,0,B,0
