Jayman on Prius Chat said the Air Cooled VWs were calibrated to run rich to help keep the engine cool. I can relate to that as when my Tempo had a failing fuel pump, it would overheat. Running lean is running hot.

Honestly, those were just not running right, and not properly tuned. A good running 1600 actually has very low emissions. My '71 Super Beetle had a 1600 in it. When I took it for emissions the paper said the maximum for hydrocarbons was 450 ppm, I had 45 ppm. So those people just needed a tune up.
