Carb running very lean

[MrXT]

Changed my spark plug and it looks like my engine is running very lean.

Does anyone know the correct air/fuel screw setting?  Although I have the agility city I'm sure the carb and engine is completely the same.

Its generally 2 - 2 1/2 its different on every different scoot. You need to find your sweet spot. I learned from online tutorials to adjust thr air mixture screw.

Do you do lots of full throttle driving? I've noticed my 250 plugs  come out pretty white if I do lots of high speed. Go one plug cooler, cr8hsa, if you do go at high speeds a lot.

I wouldn't say lots but I do push it sometimes especially up hill because I live on top of a steep one but I don't think iv ever gone faster then 55mph. Most of my journeys are usually short 10 min trips tho. I'll show a pic of my old plug soon.

Can running lean cause the engine to seem much louder than it should? My scooter has always seemed very loud for a 125. Iv noticed a small hole between the airbox the pipe thing that leads to the carb. Its a small gap in this black silicon looking stuff can I seal that with regular outdoor silicon sealant that we use on windows?

Go up a jet size and see how that goes

Mixture on the A125 should be about 3 1/2 or around there. Mixture will hardly change plug color.
