That is the type that they now started putting in so that you need a special tool which are very expensive by the way to turn it, They are called security screws. But we are more clever than that, just unscrew it out and cut a slot in it so a small screw driver fits.

This type screw is called a "one way" screw . It can be removed with a sharp screw driver and some elbow grease .

Here you go to get it out if you cannot get it out with long nose pliers:

I ordered the tool bit, thank you

I can't wait to finish setting the air fuel mixture and the idle.

Got the tool, I can adjust the air fuel mixture but it's a strange beast. When I turn it in (clockwise) it becomes rich, and when I turn it out (counter-clockwise) it gets lean. It's weird. It's on a sym manufactured lance cali classic 2013 125 cc. I purchased new in 2012. It's past warranty period. If I could figure out why the scooter is getting only 60 mpg, that would be great
