[8D] I have a bit of a problem with one of my older 1/2 A engines and I need some advice. I believe its a black widow type, .049 with a bypassed "attached to rear of motor", metal fuel tank. You know the little bowl shaped kind. Anyway, I was flying with it the other day and my engine performance became more and more erratic. I tried twisting the fuel tubing which surrounds the needle valve and which acts as a "sealer/extension". I noticed it ran erraticly but when I squeezed the tubing with pliers to adjust, it amped up and ran fine!! Ok I'm thinking needle valve air leak now! So I decided to remove the tubing from the end of the needle valve to see how it ran then. So I pull on the tubing, and out comes the needle valve, AND THE SLEEVE IT SCREWS INTO!!! What the!! So, I guess I found the air leak huh! First question is, how do I reinstall the thing? It has a little hole "port" in the side, which way should this point when I put it back in. Second, should I JB- Weld this thing back in or something? What do I use to keep it from popping out again? Any bright ideas will be much appreciated, cause I've never dealt with this issue before. Good thing it didn't fall out in mid flight, I'd never have found it!!

TIA ZZ.
