Teflon tape the cylinder head. I like to wrap mine so that once in place the tape is half in the cylinder and half out. Then fold the protruding half back over the cylinder to sandwich the tape between the cylinder and head.
Check your o-ring on your piston. I like #14 o-ring from hardware stores for normal non-boreup piston heads. But if the metal piston head has a wide gap you might have to take it with you. You might want to try a new air nozzle if you find that it is the weak link. Deep fire air nozzles fit particularly tight and their cylinder heads may be a slightly different due to this.
Parts (possible)
Deep Fire cylinder head, http://www.deepfireairsoft.com/airsoft-piston.html
Cylinder, there are many companies that use ribs including Deep Fire. Could this be a bore-up?
Piston, sounds like Modify or Echo1 pistons, http://www.modify.com.tw/products_e.html
Tappet plate, Classic Army, http://www.classicarmy.com/search.jsp
I hope this helps, it sounds like it could be about anything. My best advice is to start at one end and just rule'em out so you don't go crazy.
good luck |
Thanks for the advice, but I think I'm well beyond having advice given in cases like this. Troubleshooting is second nature to me (do it enough at work) and I've traced the problem down even further than previously (have had my share of stubborn guns, this one is definitely a pain, want it off my bench so I can work on a G3 SG1 for the same client.) I've seen some very odd things over the past few years of my being a gun tech (it's literally a full time job now one I get home from my instrumentation technician job during the day, since every weekend and evening since mid-December I've had gun work to do. (I must have made at least $600 so far, and this is the OFF SEASON!!!)
I appreciate the interest you took and the time to type, but this thread is primarily a warning to people who think the more upgraded parts, the more reliable the gun will be. From all I've seen, the opposite is true 90% of the time.
Regarding your links, ya, that's the cylinder head (he who installed it didn't even put a spot of grease on the nozzle though), didn't bother digging through the Modify or CA links though. Gonna head back to my bench now and give the gun a try after the tappet installation and see if I'm any closer.
