I'm pretty sure I've taken one apart, if only to clean something out. 
Yes, the 2 parts screw together. This may have been on a non-VW, but 
I believe the construction is the same.

Both parts are brass, so it will be obvious if he finds a brass 
"insert" in his zinc carb body.

It's quite possible that they always come apart at the zinc/brass 
interface because the zinc is softer or because of the differential 
expansion there.

BTW, if you need a larger jet, I have a set of clockmaker's tapered 
reamers that would do this job really nicely, and with great control 
and precision. You can buy a set on ebay. Like these:
