I have built four scooters, all ran different , WOW these kits are cheap and extremely poor quality, but with a little mojo you can make them run .... Main problem for me seems to be fuel /air. Either too rich or too lean. ya did the carb needle slots so don't there. Easy to richen them up, by reaming out the needle seat, but if they run too rich.... its a *****
