When I spoke with Bob on the phone, he gave me a few tips on how to gas up the Timmy for optimal and consistent performance. Will the Timmy work if you just gas it up? Sure!
But what follows is what Bob believes and practices...
HOW TO GAS UP YOUR GUN FOR A WHOLE DAY OF PAINTBALL
1. When you first gas up your Timmy for a day of paintball, screw in your tank (or turn on the on/off ASA). Your gun will pressurize and you will be able to fire it.
2. Take a hex wrench and back the set screw of your LP Reg out (counter clock-wise) until it is flush with the end cap. Do the same to the HP reg. Fire your marker a few times as you do this and you will immediately notice that the system loses pressure to the point that it will not cycle (Kinda like when you de-gas a CO2 bottle from a marker).
EDIT: Step 2.5. Turn the HPR screw in about a turn or so, just to get a little pressure flowing into the marker so you can successfully perform step 3.
3. Slowly begin turning the LP reg screw in (clock-wise) in small increments (i.e. 1/16 of a turn) as you fire the gun. Keep doing this until your main gauge reads 85 psi (EDIT: at the time this article was written, it was geared towards a Gen 2 (2k2) - if you have a Gen3, the manual suggests a range of 70-80 psi - likewise, if you have a Gen4, the manual suggests a range of 55-65 psi). Now your operating pressure is set.
4. After you have set the operating to 85 psi (EDIT: see note above), slowly screw in the set screws in the HP reg (clock-wise), until you see about 4 threads. This should put you in the neighborhood of 250-310 fps.
5. Go to a chrono and fine turn the HP reg setting until your marker is shooting at the velocity you want.
6. DO NOT DE-GAS YOUR GUN FOR THE REST OF THE DAY. Bob keeps his marker pressurized until his is done for the day. Only use your power on/off switch to disable your gun.
What this does is reset the tensions on the HP and LP reg springs. When you first gas the gun up, the gas pressure in your tank slams full force into the HP and LP regs. It takes time (i.e. many shots) for the springs to correctly adjust from a state of non-pressure, to a state of consistent pressure.
The idea of steps 1-5 is to slowly introduce pressure into your gun's system instead of 'shocking' it. Just think of the Regs as faucet valves in your sink. Be nice to them !
The idea of step 6 is to keep the springs in your regs under consistent pressure so your gun will have consistent velocities throughout the day. Good consistent spring pressure = good consistent regs = good consistent air pressure on the balls = good consistent ball trajectories = good consistent ACCURACY! Let's say you play 10 games, and after each game you de-gas your gun. That's 10 times your reg springs have to reset! How do you expect your regs to be consistent?
Bob says he does this every time he plays. But if you just want to goof around and shoot the gun, it's ok to just gas it up and rock and roll. Just don't expect super duper consistent velocities.
