LVL 10 Beta Testers,
There has been a lot of discussion about how much time and tinkering it takes to get this mod tuned in. I think there is another side I should present that will allow almost anyone to get up and go with reasonable, usable results. From doing a bunch of converstions we are finding that you should have a good chance of getting it running if you do the following steps exactly. If it still doesn’t work come to the forum and see what’s going on and post your problem.
1. Take the guts out of your power tube and put them in a bag along with your old bolt.
2. Install the backing washer (1)
3. find the carrier (4) that has two grooves cut in it and install a power tube o-ring (2) and lightly lubricate the power tube oring and the black carrier o-ring (3)
4. Using the end of a pen cap push the carrier, o-ring first, into the power tube.
5. Drop in TWO shims (5) and make sure they are sitting flat.
6. Holding the valve upright, screw in the power tube tip (7) and tighten.
7. Find the middle length bolt spring (9). This one can be identified because it has one coil cut off the end. Put the end with the coil cut off on the bolt first so the end without the coil cut off is hanging off the end of the bolt.
8. install the bolt on the valve, assemble into the marker and gas up.
9. The marker may or may not be leaking down the barrel. If the marker does not shoot, turn up the velocity until it does so consistently every time you pull the trigger. Fire the marker a few hundred times to wear in the o-ring while you let it leak.
10. Now that you have the o-ring settled in, switch to the next size smaller carrier until the marker stops leaking down the barrel.
11. Set your velocity to 280-300 and you should be good enough to use the marker as is.
This configuration should get you working and out on the field. The next step in fine tuning is to switch to the longest spring and see if you can get the marker firing reliably in the 280-290 fps range with that spring.
