2 Is any grade of petrol ok ?
3 What difference does altering the needle valve make ? Mine has 3 grooves
Cheers

The stock engine has a plain bushing for the little end so I would run a quality, synthetic 2T oil at 4%.
If you can get ethanol-free fuel, that would be best. Around here, super/premium has low to no ethanol and that is what I use. Fuel these days is not very stable. Do not store your scoot with fuel in it. Drain both the tank and the carb before storage.
Putting the clip in a lower groove on the needle, raises the needle in the needle jet which will richen the mid-range.
