T2 velocity issue
 
After SPE, I took my T2 apart to clean it. I left the pump on and didn't take out the valve. When I went to use it again I couldn't get it over 245 fps. Last week, I took the reg apart and checked the orings. (They all looked good.). I took out the hammer and there was no foreign material on it or in the chamber. I made sure the bolt wasn't upside down. (I've made that mistake before.) I put it all back together.

Today, I finally had the time to gas it up and try again.

Still cannot get over 245fps.

What could I have done?

I have barely had to even touch the reg or IVG since getting this gun a little over a year ago. I have taken it apart before. I am stumped.

It is not leaking air, so I still haven't gotten into the valve. Should I?

Set it all back to factory

Run a swab in ur lower tube.

The tolerance in the bottom tube is very right even a bit of normal grime from just regular use will mess with it

I'd try backing out the reg and the ivg all the way on a .682-4 back with our paint.. put over the crono and walk the reg in till the velocity begins to drop. Then use the ivg.

Jwalker has a box of main springs (mine) get one from him if the above does not help.
If all else fails find jacob or jordan at the field, yup the kids they are becoming quite good at trouble shooting.

Check the input pressure of your reg. it should be set at about 325 psi. Your IVG should be turned in at about 3 full turns from flush. This should get you up to speed unless you hammer spring is worn out.

Finally had some time to tear into this marker and try to fix the velocity issue.

I tore it completely apart and cleaned everything and checked all o-rings. O-rings all looked ok.

I got it up to velocity but reg is flush and IVG is about 5 turns in. That seems a lot to me. Maybe it is the main spring.

I used a .684 insert with the field's Evil paint.

I don't have a pressure checker for my reg and haven't taken the time to build one. May be something to do later this summer.

Thank you everyone for your suggestions. With some fiddling I got it up to speed. Seems that it may still need a little fine tuning, but I can at least use it for now.

What's the reg pressure at?

Sorry. Skimmed the thread

CCM factory specs are 350 psi for the reg.. I run 320-325 and 1 1/2 or 2 turns IVG with a hush bolt.
