Super Soaker Central

I drilled a bigger whole where the small nozzle used to be to make a bigger stream, now when i pull the trigger its only a short burst, would i have to increase the size of the tank in order to make the shooting function go back to normal?????

I'm no expert, but I think you drilled it too big that it shot out all the contents of the PC in one big blast, like the top trigger. The bigger the output, the less shot time you have. You could just add a PVC end cap drilled to a slightly smaller hole to the small nozzle. However, as I said, I'm no expert, and you should wait 'til a mod posts.

I'm no expert on it, but here, Ben posted how he expanded the pressure chamber of his Arctic Blast. http://forums.sscentral.org/t4743/

The arctic blast has a short pc to begin with, so you'll want to do the PC expansion no matter what you do with the nozzle.

To reduce the size, you should probably fill in part of the hole with epoxy, but make SURE that you don't get any into the area behind the nozzle going back into the tubes.

Alternately you could take apart the gun, fill in the entire nozzle with epoxy, then drill a smaller hole.
