With the 98 Custom there is a screw just past the last ';N'; in Tippmann. With the right size Allen wrench turn it left the velocity goes up, and turn it right to lower the velocity.



Things that also affect the velocity is how full your tank is. Also with C02 if the tank is cold, for example you are shooting a lot or the weather outside is cold it will affect the velocity of the marker.



To solve this problem of the changing velocity due to the C02, I'd suggest that you switch to using Compressed Air. The Tippmann 98 Custom can use both C02 and Compressed airTippmann model 98 help?
Well if you are using co2 and its cold out its your dam co2 tank. Co2 is crap and when its cold the pressure is low and you wont get your marker velocity that high. And in the summer when its hot the pressure will be high and you will have trouble keeping your velocity down.



Other then that yes the spring kit will help push up your velocity. Change out to a stiffer spring and the velocity will go up. Its a cheap and easy way to push your velocity up higher or lower by changing out the spring behind the rear hammer. You can buy a spring kit for about $6 on ebay.
Find the allen wrench(es) that came with your marker. There is a velocity screw to the right and below the last ';n'; in Tippmann. Turn it to the right to make it go in and therefore make it more powerful. Also make sure your CO2 is filled up.
