Leak from velocity adjust hole
Let me start by saying that the problem here is about one hundred percent likely to be my fault. I've been getting my pneumatic trigger finished for my tac one. However, Saturday I took all the unfinished trigger pneumatics off the marker and re-installed the original equipment.
The marker now leaks down the velocity adjust hole.
The first shot velocity is usually radically high
After a shot or two the leak stops for a moment, but returns after a few seconds
Shots taken after the first in a series can be relatively consistent
If I wait a moment and shoot after the leak returns, the velocity will be very high again
I think I'll have half an hour Friday to look at this after the broodlings are in bed, any suggestions for places to start looking would be great
Thanks in advance!
Does the velocity return to normal after the first shot? Leaking from the adjustment screw is an indication that your velocity is too high.
Yes, normal speed after a series
Chrono of 261, 270, 265 or similar on three rounds (field limit 270 for semi) then as high as 345 if a shot is taken after a pause
Ok. Type of valve? Level 10 or 7 bolt? If it's a Classic valve that you added an L10 to, it may possible have the older reg piston which cannot handle the pressures needed for the L10 to operate properly. If this is the case, you will need to contact AGD or Tuna and buy a new reg piston.
Nearly new Stock level 10 with factory ult
Everything was good in the spring, so error on my part somewhere during disassembly
So an X valve? If so, take a look at the link and make sure you have it assembled right:
I'll double check the ult, it is the only part that I removed or touched. Since the marker was working
That said, I had thought I just took it out and put it back. Still, it's a place to start, nothing else got touched
