My buddy just gave me his NX50 that he had sitting under a pine tree. After removing the sap and cleaning the carb, she runs! Still having problems tho and another friend of mine pointed me here. She idles fine when the rear brake is engaged (and thus the clutch disengaged?) but when i let go of the brake, it just opens wide and tops out @ 20mph. The CVT transmission doesn't seem to be moving at all either, but i can't be sure since there is no response from the throttle even after tweaking it. Anywho, seems like i have some work cut out for me but you can't beat free!
