Question, Needle & Air screw?

Recommended Posts

1.Needle Clip 1-5 is up richer down leaner?

2.Air screw clockwise richer counter clockwise leaner?

Help

From the top of the needle going down will richen the mixture, because you are raiseing the needle, so going from the bottom position up will lean the mix because you are lowering the needle

Turning the airscrew out(counterclockwise) will lean the mix, turning it in(clockwise)will richen the mix, if you have a 4stroke with a fuelscrew it is the opposite of the airscrew, out(counterclockwise)will allow more fuel to pass, in(clockwise)will allow less fuel to pass

1. The top position is the leanest.

2. Depends on the carb. CR, PWK, PJ, PE series Keihin carbs are counterclock wise is lean.
