RE: sucky idle problems with the Mad Max turbo roc

Yes, they can be taken apart.  There's not a lot to the insides from what
I remember.  I seem to recall a document in the VW archives about taking
one apart and adjusting (bending) the spring to allow for more fuel and/or
compensate for wear.  I expect this is the sort of thing one would not
want to undertake without a fuel pressure guage and the specifications for
CIS fuel pressures (and a lot of patience).

I actually lucked upon a brand spanking new one in a parts car I bought
recently.  They are not a cheap item...

I have also used carb cleaner, as well as canned air (for electronic
parts) with noticeable results (mixture adjustment required afterwards.)
