I don't get here much at all, so this may very well have been covered more than once.
I was having some leakage from my Magma, and got a bit tired of it. I took a very small piece of cotton, left over after trimming the wicks, probably about the size of a BB, or very slightly larger, and stuffed it down between the two screw post. Worked fine. Hasn't leaked since. Well, unless I go crazy filling it. LOL!!!
One other fix was a bit more expensive. I got in a Varitaz. Problem solved and taste even better than the Magma. Impossible as that may seem. Woo-Hoo!!!
