It is possible that was the pump.
Bypassing the fuel pump is easy just unplug it and using a piece of the fuel line run it from the petcock to the carb.
Excellent thanks for the information, it's these little bits and pieces that are most useful when buying something new.
Does failure of the fuel pump result in a no-run situation (or just poor?), and aside from eliminating the potential for problems...in their positives and negatives of having versus not having the pump? Presumably it was put there for some reason by Honda, but the later models didn't use it?
