Thanks for all the great info. My 2 kids a fast becoming pre-teen mechanic whiz's. The bike now runs fairly well. It runs good in the mid range of RPM's. Still no battery but the lights work and it will run for 20-30 min easy.
New problem I am working on is getting it to idle down. I have backed the screw all the way out so I guess the valve? at the end of the throttle cable is not seating down far enough?? It is a neat little scooter.
