Default Question about "Pinch Test"
open the throttle all the way and give the fuel line a quick pinch. If the engine speeds up about 300 RPM then the mixture is perfect. If it slows down, open the needle a bit. Also remember to make the pinch short, or the engine will die completely. And as far as I know, it is standard for 2 and 4 strokes.
