Technics + Jelco + Ortofon 2M Black PNP - headshell not level


I recently pulled my modded 1200mk5 back into my main listening room from my office. I was going through some albums last night and found myself thinking - it feels like the ‘image’ or ‘soundstage’ or whatever you want to call it was pulled to the right. I dug around for my small bubble level but could not find it, but I double checked the 1200 itself and everything was level. I switched to my other turntable and everything came back into center and was richer. 

This morning I found the mini bubble and checked the level on the headshell and, lo and behold, the bubble was all of the way off to the right fully outside of the circle. I have a 2M red PNP laying around so I checked that and the same thing although not as pronounced. I pull another headshell that was empty, and it registered very close to level although the bubble was pulled slightly to the right. 

I have a few questions: 

-anyone seen this before? 
-I’m assuming that this is likely what pulled the image center to the right - is that a reasonable assumption? 
-I’m assuming that the only ‘flx’ would be at the tonearm mounting plate - as I write this, I am realizing that i need to check more spots for level. Any other ideas? 

As always, thanks.

It's definitely has nothing to do with turntable or headshell level, probably it's your phono stage or something else. 
Still an azimuth screw on the headshell would improve things.
The Jelco 750 has an azimuth screw on the HS25 headshell.
You don’t need any special headshell with azimuth adjustment on Technics tonearm, you can simply rotate your shell when it’s locked to adjust azimuth. Anyway if it’s not completely off (which is impossible) it will not affect the sound that much, check your phono stage channel balance!
I did a few things: 
-I moved the headshell when in the arm to get closer to level 
-I upped the anti-skate (it was at half of the tracking force) to the full tracking force 
-I swapped the cables from the ifi phono pre because the ones that were going from the it to the amp were just touching 

The combination seems to have helped. Thanks to all!
