Efficiency problems...

[BIG BOB]

just got my angel led today (will have pics up later this week) and it seems really awesome so far. but as i was shooting it i looked at the gauge and could see the tank pressure descending a little to quickly. i think i got about 50 shots off of 400psi which is not very good. ill try it out with a full fill non stop this weekend but is there anything i can do to improve effieceny. right now its got a 68 3000 maxflow putting about 450ish into the gun. im eventually going to have and angel air and vigilante on thier. so any help would be greatly apprecieted. thanks

one more thing. its missing the little o-ring on the inside of the breech. could that be causing the ineficiency? also does anyone know the size of that o-ring so i can order one. thanks

were you shooting paint when you got this bad effeicency? If you didnt know, Angels use a lot of gas when you dry fire without paint. Try it with paint. If that was with paint, then it sounds like something might be set wrong. What i suggest is, since your new to angels, find a good tech and send your gun to get completly cleaned and tuned (there are plenty advertised at this forum to choose from). That way your sure the gun is in good working order and you don't have to mess with anything. Otherwise, learn how to tune an angel and grab yourself a tuning kit :)
Yeah, if you dont have the breech o-ring more gas is vented than normal, but it won't cause your efficency to drop that badly. Im not sure of the size but i know u can order them online (www.angelparts.com or www.theangeguy.com). I think its just called the Breech O-Ring.
good luck and i hope your led gets healthier!

yeah for the most part it was dry firing it. so ill see how it does with paint. any way i have the brass tuneup kit so i went ahead and checked my lpr pressure and it was at like 110. i dont want to take anything out untill im certain i know how to work on it. so any help there would be nice. thanks

110 is way too high for an LED. Your LPR should be down around 85-90 psi. 95 if you feel like pushing the limits. You need to take out a couple of shims. The breech O-ring is no real biggie....it will change the sound signature of the marker a little, and you'll lose a little air in the transfer from the exhuast port to the bolt, but not alot. It's the same O-ring as on the outside of the ball detents. Replace it at your own discretion. Eric at AngelParts.com has plenty of O-rings. He is supposed to be leaving for Chicago today, so give him til next week and then call him, and I'm sure he'll hook you up.

Make sure your dwell is set properly.

Also you may want to consider getting LCD internals (LPR and Valve, etc) put in to your LED.
