Re: herro, i think i might be having some stem problems
hmmm, this is weird, I'm a little thrown off now. I think the vendor might have mixed and matched a different stem to that Mya Gyro vase. Still, if you check for an air leak, and it passes, then it should smoke good. Try doing what I told you before. Plug the other two hose ports. Insert a hose into the third. Place your hand on top of the bowl. And try to suck in air. If you can't suck in any air, then it means that it's air tight, and because of this it should smoke good with no issues.
I know that Mya necks (the part where the hose ports are) can have the other ports subtracted or added. Do you have the covers for the other two hose ports?
