Don-Ohio: I got your message from Expressely Mopeds by email but the forum seems to be down quite alot there. I took the carb apart today - the float is working fine. I bought some carb cleaner and will clean it tomorrow. Fred's article in resources is interesting - will try some of that tomorrow as well. Recommended oil is Honda injector oil - I'm using just plain 2 stroke low ash oil - will investigate source for proper oil.
Zippy: I can't recall right now whether there's an adjustment lever - I'll look tomorrow. Might buy an inline fuel filter aswell.
I'm expecting new headlight, junction box, battery isolator and lots of other goodies in the post tomorrow - looks like I'm gonna be busy!
Anyone got ideas about where to attach a vacuum gauge?
Also, still need a switch layout grid for NU50 ignition switch.
