I've attached a photo of the carburetor assembly I removed from the motor. I'm going to clean them up over the winter. The question is regarding the hose in the photo, with red arrow pointing to it, and where it is supposed to attach to? I remember seeing this hose unattached when I bought the boat back in September. The engine hasn't run right and this hose might be a good reason why. I'm sure the carbs need cleaning as the guy I bought the boat from said it sat for about 2 years. Anyway, it seems to be a fuel line so it might attach to somewhere else on the motor. Any advice?
