As indicated previously, the VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover who did lots of testing), but they are usually jetted a little leaner than that, so the X127.5 is really a minimum jetting for the 1600cc engine. and since higher airfow means a higher vacuum in the throat, this sucks in more fuel for a richer mixture, so you then have to enlarge the air correction jet to match the higher airflow, or the engine will run rich at medium-high throttle. For the 009 distributor and the 30PICT/2 carburetor, you need a X127.5 or X130 main jet and a smaller air correction jet - about 100-110Z.

Try to use the leanest main jet you can -- too rich will only result in the cylinder oil film being diluted more, and this means higher cylinder wear. Once you have those two sorted, then try a faster run and from 60 try flooring the throttle - if you get a good smooth response the air correction jet should be OK, but if it tends to stumble a little or feel breathless, then either the main jet is a little small or the air correction jet is a little large.
