yeah i had the old 98 custom so i had to change out the powertubes and all that stuff. the velocity screw will not go in and out like it used to do you think that could be a problem? im completely lost because i cant find anywhere to get air because dicks sporting goods has no clue what they are doing when it comes to filling co2 tanks

So have you tried my other suggestions? Oiling the plunger,adjusting the screw on the RT, using a full tank of air?

The velocity adjuster can have an affect on your RT but only if you are using co2, it is extremely cold outside, and you have your marker turned up past 300fps. The lower the velocity is, the more pressure you will have behind the RT piston. Besides, why can't you adjust your velocity? Do you have it thread locked in there?

Do those things that I have mentioned already and see if that solves your problem.

idk when i took my velocity screw out of my old tube and put it in my new tube it would go in the same way that it would in the old one. idk what is wrong with this damn thing, but im trying to figure it out. it looks like i may have to go to hpa. can i use an expansion chamber with hpa? because ive already got one on my gun from where ive always shot co2 out of it

Well, first of all...HPA will not magically solve all of your problems. YES it is better for your marker and Orings and you will experience better accuracy and shot consistency. BUT I don't think making the switch will solve your problem.

You can use HPA with an x chamber but you will not be able to go past 265 fps or so. It won't damage the x chamber if that is what your asking. I would just stay with co2. But its up to you.

Right now I would worry about getting that RT working right. HAVE YOU TRIED ADJUSTING THE ROF SCREW THAT IS ON THE RIGHT SIDE OF THE MARKER? HERE IS A PICTURE IF IT WILL HELP YOU:



I have the RT Adjuster screw circled in RED. You use this screw to increase/decrease the ROF (rate of fire). If this screw is turned in all the way (too tight) your marker won't even shoot. The trigger will be REALLY hard to pull. YOU MUST LOOSEN THIS TO ACTIVATE THE RT. Also please see the diagram to see where to put the lube I am talking about.

REMEMBER: if you do not have sufficient air to power the marker, your RT will most likely NOT function.

Yep, a good place to start is with making sure you have a full tank of air available. Also, tear the gun down and lube that piston up, since that is the only moving part of the RT system itself. It is also a good idea to use teflon tape on any threaded fittings along the air hose system, since that will seal up anything better than orings could. Speaking of Orings, make sure your Orings are lubed up as well. Once that is out of the way and the gun is put back together, put a few drops of oil down the ASA and air up the gun. If it fires but the trigger is very difficult to pull back, loosen up on that RT valve above the grip on the right side. But only go half a turn at a time until you are in the ballpark, then you can move a smaller increments to fine tune. Do this until you are able to easily "sweet spot" the trigger and get at least around a 5 shot burst.

If you are at first able to fire the gun, but the trigger doesn't bounce back and is very easy to pull back, you need to tighten the screw on that valve. Again, keep adjusting in half turn increments as before then fine tune.

Here are a couple things to keep in mind. If it is anything below freezing, your RT will work for a bit but the lines will freeze over from the quick firing and your piston will gum up. You will lose your automatic fire until the system has thawed out. Don't worry because there is no damage from this happening unless you got that thing REAL cold. I played in this state for 2 hours on semi auto after I lost my auto fire.

Also, quite a few people do have problems getting used to the sweet spotting theory. I have had friends of mine pick up my gun and can't fire a 2 round burst to save their lives, and they will tell me it needs tuned. I will pick it up everytime 5 seconds later, rip off a string of 10 rounds in a second, and tell them, "Why? Because your gun is electronic?" So once you get the system firing small, small bursts get a feel for how the trigger is moving depending on the amount of pressure you are place on that trigger. It is one of those "practice makes better" deals. Once you get the hang of it, tune that baby up and let it rip!

You mentioned that your velocity screw doesn't screw in like it used to? You might have that cross threaded from when you put it back in. Double check that and let us know what happens with your 98. We will get you sorted out for sure!!

i have checked and double checked every connection, and i have opened and closed the adjustment screw all the way...the rt pin that comes out behind the trigger will NOT move at all...so it has to be lack of air right?...thats the only other thing that i can think about...and i have no clue where to get my tanks filled RIGHT because i have been to TWO dicks sporting goods, and neither one filled my tanks right. idk what else to do

A good place to check is any hardware store. Most will fill for you.

Even better though, would be to check any fire extinguisher service shop or fire departments. They have to fill fire extinguishers all of the time and most of them USE CO2!!! I can almost guaranty that they will do it right since that is a pretty important safety thing with fire extinguishers. Call around and see what they say. Most places would be happy to do it. And if all else fails, there is always Walmart....

do you think they have the right equipment to fill paintball tanks though? ive got a fire station like an 1/8 of a mile from my place and ive never even thought of that

They should. I know a guy who lived the same distance from my place back in my hometown and he filled fire extinguishers for the town. He also filled my CO2 tanks. Just give him a call or just talk to them and ask.
