Opps sorry I somehow deleted the results of the second test on a very
warm engine.  It still failed after freeway driving.  HC was still
over the max of 220 at 437 PPM versus 469 PPM cold.  CO was 2.83% cold
and 1.577% warm.  The CO2 on the first test was 12.94% and O2% was
1.46% at 2500 RPM.  At Idle it was CO2 at 11.37% and O2 at 2.07 %.  It
appears we don't check NOx anymore here in Salt Lake.

I had always heard that the older VW  aircooled engines were designed
to run slightly rich to enhance engine cooling.  Anyone care to
comment on that.  My mechanic is an old VW guy from way back and I
feel he knows the engines.  He completely built it last year with new
heads and all. So i am having him take the first look at it this week
while I'm working, hoping its just a small adjustment.  Will report
back.

Cheers,

82 westy
Thinking of mounting my 1976 Lincoln Continental Mark IV's large
chrome grill onto my 82 Westy, as soon as I add a radiator for the
460.  It fits the front vanagon contours well.
