Our 1976 T2 Type IV passed NCDOT smog with flying colors for three years
straight at the factory settings, even when running 96mm pistons. Our
1982 T3 Type IV Westfalia does the same, and my (former) 914 (MPC
D-Jetronic) was the same. Factory settings, low smog, reliable lifespan.
I'm not sure how one would accurately lean the mixture on an AFC Type IV
engine, short of changing the factory-set spring tension on the air-flow
meter. The CO screw doesn't adjust the mixture, per se. How do you make
a type IV run lean, Stan?
Nevertheless, I've found that if the motor is properly tuned (by the
dealer in my case), and set up to VW specs, your smog numbers will be
suprisingly low, and you won't experience any "self-destruct".

Someone gave me a site that had the numbers of various VW models brought
into the US but I crashed a drive and lost my favorites list.
I'd almost bet that the metal vents collect more air than the plastic
vents (reasoning; I bought an 81 from a heavy smoker and it had
disassembled cigarette filters clogging up the fan and burnt filter
fibers throughout the hot spots in the cylinder area. The engine was
also
coated with an engine oil and cigarette ash mix.)
Seems that 81 was a good year for Vanagons. Wonder what happened. I see
very few 82 or 83 aircooled Vanagons or Westies. Possibly 81/82/83 was
when the domestic Mini-Van got into high gear.
I know one thing for a fact. If you try to run a type IV engine set to
the lean settings required to pass state inspections your engine will
self destruct from lean burn detonation and overheating that causes your
valve seats to drop out.
