Well yes, but you would be adjusting only closed loop operation, which
is idling and before first micro switch kicks in. (have a look at:
http://www.eurowires.net/wst_page6.html ). After that point, in open
loop, that adjustment has no effect. CIS E cars are usually affected by
lean conditions after the enrichment micro switch kicks in (after
aprox. 4K), and for this problem you can get enrichment kit. Since your
lean conditions are before enrichment switch point, you should look
into micro switch operation first.
If you really want to adjust it and experience the effect, use the tool
and mark starting position (so it can be returned to) and take it as 12
o'clock. Turn it CW to 1 o'clock or even two, and find the difference.
Idling should get uneven and rough. However, test the car and find if
the knock is affected. If it is, it means the MS is not working. After
that, return the adjustment to starting position.
