I have found that I get better results if I perform the whole usual tune-up
procedure, then put the air cleaner back on, then readjust the mixture to
get it just right.

Also, I find the idle slows down (mixture richens) when I put the breather
pipe back on the air cleaner so I always set the idle about 50 rpm higher
than what I want to compensate.

The behaviour that you are experiencing almost makes it sound like the carbs
are icing up, but I have never heard of that with dual carbs on a VW before.
