Yes the port on the intake manifold is it.....baring any leaks.
By backing the PMS
out, you make the pilot
If the carb
has never been jetted, and you have the pipes and a freer flowing intake, as well as the ported manifold, you probably are lean. If your other carb is almost done, you could back the PMS out to 3 or 3 1/4, and see of that helps yo get you by. If you want to get by, you could also put a second washer under the plastic spacer on the needle for a total of two. That'd give you a half step richer in the overlap. The washer, and the PMS adjustment will probably help until your other carb is finished.
Without having any idea where you are in the carb, ie completely stock or if someones been in there already, we're all just guessing.
