Adjusting the cueing mechanism on a Mørch tonearm


Greetings!
I've installed a Mørch UP-4 tonearm in a new arm board on a VPI HW-19 Mk 2 turntable. Even though the arm board is entirely flush with the acrylic base plate, the cueing mechanism is a bit too low such that the stylus doesn't clear the record rim. Is there a method for adjusting the height of that tonearm's cueing device? I can't find anything online and a note to the distrbutor gave me the not too satisfactory (but maybe only) solution of installing a washer under the tonearm base plate. That would throw off the azimuth. Advice appreciated!
Thanks,Keith

Mike,
Thanks for the reply! How does one go about adjusting the rear height of the tonearm as you suggested? All I did was insert the tonearm base in the Mørch specified 20mm hole I had drilled in the new acrylic arm board so it was flush with the surface all around.
Thanks again!

Super helpful advice. I’ll get going on that
projet tomorrow AM and ill report my success or Failure

Thanks to all! The jargon for this hobby is really comprehensive. I was referring to the horizontal plane of the headshell which I incorrectly called "azimuth". In medical ultrasound (my former area of "expertise"), azimuth referred to the plane of the ultrasound beam relative to horizontal; hence, the confusion (in part).

Thanks to all! Yes, the height of the Mk 2 platter is greater than the acrylic platter on the old turntable. That accounts for the problem.

I'm hoping to get together with Eric this week or next (if possible) for final adjustments and listening to the Magnepan LRS speakers I recently acquired. Maybe also time for a brief excursion to nearby Music Millenium, too!
Thanks,Keith
Here’s an update on my Mørch tonearm saga:
I'll preface this with many sincere thanks to the ever knowledgeable Eric (aka bdp24) for his tireless work on this project and his expert advice and help!!

1) Hans Henrik Mørch personally responds to questions. He was prompt and very helpful. Hans misunderstood my original question; hence, the initial suggestion of placing a washer under the tonearm base. The US distributor for Mørch, SoraSound, supplied me with a PDF of the mounting template.

2) There is a small (1.5mm) Allen set-screw at the base of the tonearm which is very discreetly situated. While I’d noticed it, I didn’t know that - by simply loosening it - the entire arm lift mechanism can be moved up/down. It’s all perfectly aligned now.

3) As I mentioned in an earlier post, I wasn’t using the term "azimuth" correctly. By slightly rotating the eccentric counterweights on the tonearm, I was able to align the cartridge so the sides are now orthogonal to the record surface.

4) To clarify regarding the new arm board, Kinko’s didn’t print the UP-4 mounting template exactly to scale from the PDF I provided. I should have measured it myself before having the new arm board drilled. An oversight on my part, of course. I got another new and perfectly matched acrylic arm board for about $30: very reasonable. I recommend Tap Plastics in Portland. They did a good job and the work was done in about an hour.

5) The MK 2 sounds very fine indeed through my recently acquired LRS (replacing Vandersteen 2C).

6) My next step may be replacing the Mk 2 suspension with either Herbie’s Tall Tenderfeet or maybe the IsoAcoustics Gaia III. The Herbie’s are much less expensive. I’ve not seen a performance comparison between them.
