lets start with the oils; for the air cleaner [ foam type ] after wash out with petrol you use whats called air cleaner lube. for the engine ; use shell advance 10w 40. now the needle ; the needle is visible when you undo the center top carb cap where the cable is attached, when this is undone and withdrawn from the carby you will see both a slide with a needle attached, there is a small U type clip that holds this needle in position, the needle is adjustable by removing this U clip and re-positioning it to another slot on the needle [ 5 slots ] try this setting with the clip on the very bottom needle slot. hope you understand this .

the air / fuel adjust screw is positioned at the front side to manifold of carby and is adjustable by a very short 40mm screwdriver, this adjust screw is also positioned to a north south direction not on the side of carby.
