How do you adjust lean carbs?
First, turn in the mixture screw until the engine dies or runs worse, then back out the screw (recommend turning ¼ to ½ turn at a time). The engine should pick up speed and begin to smooth out. Back out ½ turn more, or until the screw does nothing or runs worse then turn back to the point where it ran its best.
How do you adjust the air fuel mixture on a motorcycle carburetor?
Tighten the fuel mixture screw by turning it clockwise. This will decrease the amount of fuel getting in, i.e, making it leaner. Turn the screw clockwise, stop when the engine starts sounding rough. Running on a lean mixture makes your bike idle at lower RPM.
How do you adjust the idle on a 2003 Harley Davidson?
Turn the screw clockwise to increase idle speed and counterclockwise to decrease it. Your tachometer will give you the idle speed, but if your bike isn’t fitted with one, then play it by ear; if you go too low, the bike will either cut out or stumble when you twist the throttle, while too high and it will sound wrong.
Why is my Harley sputtering?
