I heard from Karen Davis that her problem with high HC in her CA SMOG
test was solved at BusLabs with a timing adjustment.  Since her problem
symptoms were similar to mine, I would like to try and adjust the timing
or at least check the timing on my 1.9L waterboxer.

How can I try this myself?  Is this documented in the Bentley manual?
Please advise.

Damon Campbell said that BusLabs adjusted the fuel air mixture of his
2.3L waterboxer.  Before the adjustment, the symptoms were similar to
mine.  I would like to try and adjust my fuel-air mixture too.  How can
I do this?

I've got the Bentley at home and I'm at work now.  I'm trying to collect
the info so that when I get off from work, I can try a few things on my
1.9L waterboxer.

Thanks.

Regards,
Craig
