TES adjustment for Burping/Auto Fire/Runaway
The key to remember is that the harder the velocity spring pushes the striker forward the more air pressure you need to re-cock the marker. The combination of a hard re-cock spring and high air pressure causes a violent firing cycle, then massive trigger response or auto fire or runaway or failure to re-cock. The answer is to reduce both the re-cock force and air pressure, creating a smoother firing cycle worry free shooting. So here's the steps:
To start it's assumed your striker and sear is stock, no mods or polishing completed. If so check to see if you rounded the peak on the sear that would stop the striker. It needs to be a crisp 90 degree angle for a polished striker, if it isn't that needs to be corrected before you go any farther.
Next I recommend using the velocity shim kit and spring kit for Spyders by Shocktech instead of stretching and cutting springs. These will come in handy later if you plan on using your TES through cold temps. www.xpaintball.com/shocspydshim.html www.xpaintball.com/spydshocspri.html
Next, set the regulator. Normally I start at 450psi, but as the days are get warmer you may start at 400psi.
1. Shoot across a chrono, record your speed
2. Turn you reg set screw an eighth of a turn in, clockwise to turn it down
3. Shoot a couple times to relieve the reg pressure
4. Shoot across the chrono again, if the velocity went up you’re on the other side of the reg peak, repeat steps 2 and 3 until the velocity drops when the reg adjustment screw is turned clockwise
NOTE: When you have the velocity following the reg adjustment, screw in=velocity goes down, screw out=velocity goes up you're reg is set correctly.
5. Replace the stock velocity spring with a weaker spring or smaller than stock spring shim, you can start as low as you want, I recommend at least one level stronger than the weakest and but leave yourself at least two stronger springs to go.
6. Set the velocity by the reg between 270-285fps (ignore the pressure on the gage)
7. Replace the spring or shim to one level stronger
8. Chrono under 300fps without adjusting the reg (you're leaving the reg for fine adjustment after the burping and re-cock issues are corrected)
9. Test fire, if it's over 300fsp go lighter on the shim or spring, you're goal is 295 by spring.
NOTE: If it burps the air pressure is too high. If it fails to re-cock increase the air pressure
10. When you chrono between 295 -300fps fine tune it using the reg.
NOTE: When you get it right you'll have a controllable trigger bounce but it's a fine line from trigger bounce to runaway.
By bringing the fire and re-cock cycle forces down together the TES runs great. Let the pressure end where it does. If you find you've completely lost your trigger bounce it's due to a light recoil. Simply increase both the spring strength and air pressure together until you get the bounce you want.
In the end my TES is running 293-297fps at 300psi. I ran over 1500 balls through it after this adjustment procedure with zero breaks, no burps, no issues.
