John, have you read the owners manual that should have come with the bike? The info should be there.
If not & as my knowledge of Chinese scooters is limited, I would be looking for an access point through an obvious looking removable plastic panel either at front of the bike where you place your feet or else underneath the seat in the seat bucket.
If you can't find one then get underneath the bike & look for the front of the engine, the sparkplug lead should be visible enough.
