OK, Cyrille...
Let's try again, then! :):)
There is a "balance" between CO and HC
which can be altered by doing as little
as changing the ignition timing by a couple of degrees.
A little more advance, and we eat up
CO to produce a little more HC. When
it's the other way, it's the other way.
However, this can only be done to some
extent, obviously. :)
So, we have your CO number and
lower criteria. But, what is the upper
criteria for CO.
And...
what is the stated testing criteria into
which you must fall for HC (high and low
numbers, please) and what is
your present HC emission.
