Does the a/f screwe affect the over all mixture or is it only the pilot for example let’s say I turn the screw all the way out would that make my main jet lean
@declan No won't affect anything above idle and possibly 1/8 throttle.
The air is regulated over the entire throttle range, however, it doesnt matter much/signifianly up top. Its primarily used to finetune from idle up to where the idle curcuit is beeing overlapped by the needle, at around 1/4 throttle.
@jens-eskildsen thanks dudes
