cartridge set up


last time i asked this question here i was advised to use my two points protractor.
i have n official one from ’well tempered’ arm turntable and arm which i use.
the suggested instruction i got here was if the the cartridge on those points tend toward the spindle to move the arm forward, and opposite if it tend to the other side.
the thing is that i got several time a strange result which on each of the points it tend to a different direction.
i think that there is a third factor , the angle of the cartridge on where it mounted (forgot how it’s called) , which can be can be rotate on my arm.
so i cant succeed to find the optimum set up.
will appreciate any advice/help.
is there a way to add photos?

Buy yourself Dr. Feickert protractor, it's for all cartridge, all turntables, all tonearms. Choose the geometry you like (there are 3) and adjust everything properly. PS distance is measurable too. 
You have to find the specs for your new arm. Who mounted it??
If you can tell me the effective length of the arm (distance from pivot axis to stylus) I can tell you the approximate overhang. The Feickert protractor will work if you feel like spending the money. 
it's called "well tempered classic arm upgrade"
a new black platter and black arm.
i was on a trip to California around 1997 and collect it directly from their office in Palo alto.
with instruction how to mount it,
i did the mounting for the original and for the upgrading.
i am not quiet sure i understand your meaning of  "distance from pivot axis to stylus".
as  i said , the headshell which the cartidge mounted on has the option to rotate the cartridge.
so every different angle will give a different distance from the pivot to the stylus.
if there only an option here to upload photos .
here there are some pics.

on the instruction pages that i received for the upgrade it doesn’t say any thig specific for the overhang and rest of the set up.
only at the end of all mounting adjustment instruction: " fine tune all adjustments".
it can be interpret that nothing is changed compare to the original overhang instructions, but i can't be sure about it. 
I think WT, the company, still exists. From them you should be able to obtain the necessary specifications for your tonearm. From what you wrote I am not at all sure I understand its  provenance. But for any pivoted tonearm there will be a recommended pivot to spindle distance, stylus overhang, and effective length. To use any protractor that is flexible for all types of tonearms, including the Feickert protractor, you must have at least two out of three of these data points. So your job is to find those out. Also, if my memory serves me, at least the well tempered reference tonearm has fixed holes in its permanent headshell. And the tonearm mount is a single hole drilled through the chassis. So the pivot point is fixed in space and where the cartridge sits on the headshell, that also is fixed. More conventional headshells have slots that allow you to slide the cartridge back-and-forth to obtain proper alignment. In your case it may be that the only parameter you are able to adjust is headshell offset angle. That isn’t the greatest situation, but at least it limits the degree to which you can get this wrong. By the way, getting it wrong by a small factor is no big deal.
