Well god damnit man i'm getting pretty frustrated with this vaping technology.. So far i've only been running my new solo with a 14mm pvhes gong, I decided to try a session with the stock stem (they sent me 2 new stems with my warranty replacement so I now have 4), I chose the NEW straight one they sent me. Couldn't seem to get it in easily so I took out the o-ring I added from PV. It still went in pretty stiff with some force after heating up.
Ran that session fine and decided just now to try the gong again but it has basically ZERO grip, slides in if placed above and falls out if turned over. I put the o-ring back in and it was a LITTLE bit better but still super loose, falling out easy. I took a closer look and it does seem that the NEW straight stem is slightly larger which explains why it's tighter, however the NEW bent stem and the other 2 old stems are all the same slightly smaller size and they ALL are super loose now. The bent stem whirls all around now and easily pulled out.
I'm not sure what is going on. Did the o-ring possibly mess up the stock black ring? I do notice that it's not flush anymore and parts are pushed in on the sides. It seems like once I put in this thicker stock stem, it loosened up the oven area to the point where the rest of my stems don't fit anymore... just this one straight stem.
Now i'm worried about ordering any other stems because how will I even get them to fit?
I REALLY hope this one doesn't need to get sent in too.... It heats up and charges perfectly.. just now I have to hold the other stems still with my hand. Turning the GonG upside down for my bubbler is impossible unless I hold it still in the solo, which gets hella hot.
I'm also testing this all while the unit is COLD, so it's not like they are stiff and loosen up with heat as is known. With heat it's like the stems covered in butter.
Picture to see the stock black ring, does that look fine? Any ideas why the o-rings aren't helping anymore? (i've got a few from PV and one from Pipes and tried all of them)
EDIT: comparing it to the picture I took of the oven in my other unit before it went in for warranty, they both look about the same. The old unit was snug as a bug with the o-ring but had some major heat issues which is why it was sent in.
