Just picked up a 1982 NU50 for $260. Runs strong, but it needs new tires, probably a carb rebuild, and an airbox. I started it by manually choking with my thumb; I'm hoping that a thorough cleaning will free up the choke. Is this like the Puch choke, where you turn it on manually, and turning the throttle turns it off?
The missing airbox is a concern; does anyone know if the Puch Bing High Flo sold by 1977Mopeds is a good fit?
Any other hints, either for an air cleaner, or carb/choke repair?
I also have a sticking front brake- I'm hoping cleaning and relubing the cable will fix this. The brake doesn't seem to work, so there may be more to it than that.
