Low velocity issues.

[steve_81]

Cant seem to get my Classic valve to shoot above 233 fps. I just put all new fresh o-rings in and oiled it up but it will not shoot above 233 fps. It has Hill's efficiency insert installed. The velocity nut is screwed almost all the way in. Any suggestions?

take the insert out and rechrono, see if that's the problem.

It sounds like you can't get enough tension on the regulator springs to get to the higher pressure required to use the smaller chamber. Try adding some washers inside the adjuster so that it can push the regulator assembly in farther before the nut bottoms out.

Thanks for the suggestion. I will try that out as soon as I get more air this weekend. I'm going to spend the day at the field trying to fix the problem. It makes sense. The velocity continued to rise as I turned the velocity adjuster in until I couldn't turn it anymore. Is there any other thing that I should check as well? I will update this thread Once I try all that is suggested.

any pics? wat kind of velocity adjust is it?

The velocity adjuster that is off to the side is the one that was on the valve when I initially tested the valve. I put a different one on it afterwards to see if that would work when I go to diagnose it this weekend.
