If you want, I have the parts book/list for that machine..
It's a PDF file so I'll have to send it to you via email..
On my 11/30 it has adjustment via the cutter engagement lever (The larger lever), It has a nut on the end of the rod ( the section where the clutch drive plates are in the pic)
Or I can move it up to a 2nd hole...
Below is the front page of the list.
