While I was working on my PC800 the other day I discovered that the carbs had gotten gummed up while it’s been sitting. This is the result. Fuel leaking out of the plastic tree between the two carb bodies. I pulled the bodies off of the bike, opened the float bowls, cleaned out a little bit of gunk that had built up and exercised the floats, put it back together, and it was fine. This is usually an indication of a stuck float valve or a flooded float body. It’s an easy enough fix to do in an afternoon.
