need weber help

[dub88acc]

just got a :bow: weber :bow: and i want to thank evryone one in this site who convinced me in getting one. But what do the idle mixture screw do? and the idle speed screw do? how do you tune the carb? oh and also what other air filter can you put on the weber?

the idle mixture screw adjust the mixture at idle and low RPM. the idle speed screw adjust the idle speed.
talk to A20A1 about the tunning.
