Kalibrgun cricket valve lock
« on: December 14, 2016, 01:11:54 AM »

Hi,

I'm having a problem with my cricket, when i fill the reservoir above 230bar the valve locks and it can barely put the pellet out.
If i fill near 300bar the valve blocks completely and no air at all comes out. Any help would be apreciated. Sorry for my bad english I'm from Portugal.

After stripping the gun I found that a an oring on the power side of the regulator was bad. Waiting for a new set of orings to arrive, reassemble and test. Since the gun is dismantled I'm going to give the parts a polish and try to set the regulator and valve spring to shoot the  .22 jsb 18.1g at 880/890 fps. Cheers ::)

My Cricket 22 std is set to send JSB 18g @ 880 fps.

The regulator is set to 125 bars using a tester.
Valve spring retainer is set to 1/2 turn CW after contact is made.
Transfer ports are : valve housing = 4.56mm , Barrel = 4.5mm , breech = 5.25mm.

Thans Greg,

New orings arrived and mounted. Valve lock problem is gone. I'm  using the calliper method(53.7mm) to try and  set the regulator at a aprox. 125bar. Since my caliper is not digital is a matter of trial and error to get the right pressure. With a hand pump it's not an easy job but slowly I'm getting there. ;)
