Bob,
The reason your CO is high with the timing advanced is that as the
timing is advanced, the throttle (or idle valve)has to close more to
keep the idle speed down. This causes insufficient air and turbulence
for a proper burn.

for my nickel here, I'll move this a little toward vanagon fact, since I
may
have been the culprit who mentioned "tuning" my van specifically to pass
emissions, then returning it to 10-12 deg. advanced at 1450 rpm, as
TIICO
suggests. Nobody bothered to ask any specific questions about just what
"failed", to what degree and what numbers were recorded on the I/M
Station
Report.
%OC/2 HC CO %
Max measured Max meas Max meas
idle: 916 12.1 4.0 220 96 1.20 0.27
2500 rpm 13.5 2.4 220 33 1.20 0.08
When I initially took the van in, at 10 deg adv., I was over the CO at
1.23
at idle before my "adjustment", grievous. I drive an '87 Van, an '89
Buick
about 10-12K annually. They both pass emissions annually, cost less than
$100.00 to register between them, and I help keep 160 tons of CO, 13
tons of
HC, and 6 tons of NOx out of the atmosphere here in Salt Lake City,
annually. Period.
Speaking of environmentalism, anyone here interested in helping me and
my
friends in Moab get rid of a little damn: http://www.livingrivers.net/
