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.
