There is a Haynes manual that will explain it all. It has info from
the factory books. Basically, the emulsion tube effects ,by
placement of the holes , if you will run richer at different rev
ranges (ie can fix a flat spot in fuel delivery) , the main jet
effects all running (other than idle), the air corrector jet is for
fine tuning.
To tune start by looking in the book to select a suitable main jet,
run it, take a plug cut, then adjust main jet size until you are
close. Then figure if you seem to have any flat spots, determine rev
range and drill/fill/exchange emulsion tubes until you have those
removed, then adjust air corrector until it's perfect. After that
you are good to go, NO MOVING PARTS to wear!!
