1. That is most likely a vacuum operated petcock on the scooter unless the tank sits lower than the carburetor.
2. Depending on buggy or scooter, the GY6 engine may have come with a 6-pole or 8-pole stator. There is no way to really tell unless you pull the flywheel. These are easily changed, but you must have a matching flywheel for your stator to work properly.
3. Gravity feed is sufficient to get fuel to the carburetor, but many vehicles have restrictive petcocks, filters and lines. Replacing the hardware and upgrading to 1/4" line will help flow. The tank also has a breather vent typically in the fuel cap. if this vent is clogged, it will cause poor fuel flow.
