Hey all. I have a minimag valve whose velocity has a bizarre problem. It is unable to fire between 180 and 316 fps, though it seems that it can be adjusted to go above 316 or below 180. I have been using Co2, though somebody recently told me that was bad for the valve. Is that true? When I first bought it half a year ago, the factory chrono slip said it chronoed at about 280 fps, so I assume this developed over time. Does anybody have any idea what could be wrong with my valve? Thanks for looking, and I apologize if this is something really obvious, but my instruction manual is 400 miles away right now.

get a rebuild kit and change the battery on the chrono. 4 drops of oil in the asa before you set the speed

Chrono is definitely not the problem, pretty sure another chrono confirmed this, and the chrono chroned in a lot of other guns that day properly. Meanwhile, you think an o-ring blew inside, druid (hence the rebuild kit)?

Can't hurt to replace a few o-rings and completely re-tune your gun.

well if it won't get up to pressure to be able to get up to speed, that means that either the valve isn't completely charging (leak) or here's a blockage somewhere between the tank and the valve.

Have you tried a different tank on it? Try HPA and see if that fixes the issue first...

possible problems

1) your C02 tank has somthing wrong with it.
2) your chrono is out of batteries
3) your O -rings are old / damadged.
4) you have dirt/buildup inside your regulator.
5) your marker sucks.
6) you suck.



now remember that "5" and "6" are only applicable If you can succesfully remove "1" to "4" on that list.
and that only "6" is applicable if "5" is not the problem.

and I'v never heard of a problem with C02 and a minimag valve.

Make sure you have watched ALL of These: http://forum.specialopspaintball.com/index...howtopic=153817

videos 1-6 talk about the marker, and all the parts known to it.
video 7-9 are trouble shooting.

watch them all. you will learn alot.
90% of the problems with a 68 automag are true of ALL automags.

You need to strip your valve down and remove any debris you find in there. Bulk CO2 bottles get a lot of debris in the gun. Replace all the o-rings and re-grease the spring pack (under the velocity nut) and finish a little oil. Retest and it will shoot fine. Since you are using CO2, I would recommend that you tear the valve down after a days play and gently remove any debris you find with a pick and a soft cloth. Use care with the pick around o-rings. If you switch to n2- your gun will run alot better and it will cut down on maintaince.

When I die, I want to go sleeping peacefully like my grandfather did.......not screaming like the passengers in his car.

Thanks for all the replies. After getting a chance to strip down the gun, I think I know what the problem is: a while back the on/ off valve somehow got out of whack, and I think I reassembled it incorrectly. However, I'm not sure how to remove the on/ off valve from the gun to check. Thanks again for reading this.
