RE: fuming....
Ya know I would send it back to T.C. with a letter of explanation. They are the greatest Co. to work with I bet they will fix your problem and ensure that it dosen't happen again. I bought a black dimond when they first came out and kept getting rust around the ignition area. Well they redesigned that area of the gun and sent me a new one. I have had nothing but a good experiance with them. Maby its a problem they don't know about or you could have a flawed gun. Give them a chance see what they can do for you. Good Luck Mike
