  • Villiers Carbs.

    Can anyone explain how to measure a standard needle setting of "50mm out" on a Villiers S25 Carb fitted to a 20DC. Is this measurement really a "good" starting point??
    Thanks.

    Simple, the measurment is from the bottom of the slide to tip of needle. If set at recomended measurement 1.95 inches (49.5mm) it should be fine. The needle should be a 3 1/2 taper (the standard for most Villiers S type carbs)
    Other settings are.

      Thanks John

      Hey, thanks John. Much appreciated - by the way I can strongley recommend the use of an untrasonic bath for cleaning carbs. The one I have access to worked very well.
