The autolube is linked to the throttle cable. Somewhere behind the glovebox & the bodywork the cable is split into 2 lines from the throttle cable. One part goes to the carby, & the other goes to the autolube shown below.
That pic is from the "How To" link I previously posted.
The autolube is bottom left there with the hose going to it from the oil reservoir, & the cable going to it which can be adjusted. When I was using that with 70kit I set mine to = max when the throttle is at max, but I think it still wasn't enough.
Which is why I went premix.
You'd be better off buying yourself a Gregory's Scooter Manual which covers the regular types of scoots out there.
