I changed the main seal on my .22 gamo air rifle when l put the rifle back together and break the barrel to **** the tigger l now find the trigger does not engage?

Sounds like you left a spring out. As the piston goes back, it get to a place where a spring locks a sear in place that is connected to the trigger.

My vantage np has very little pressure. Will not fire the pellet.

It is either the o-ring seal at the break barrel, or the the piston seal, or that the nitro piston is leaking. Contact Crosman direct using the link at the bottom.

Nitro Piston

A recent innovation introduced by Crosman is the Nitro Piston® power plant in which cocking the rifle moves a piston to the rear, but instead of compressing a spring, a gas (nitrogen) in a cylinder is compressed. When the rifle is fired, the compressed gas propels a piston forward to compress air in the receiver behind the projectile. The advantages of the compressed gas as a power source (sometimes called a gas ram) include lighter weight, a great reduction in noise and vibration, and the option to leave the rifle cocked for extended periods which might cause weakening of a spring.

Is my crosman shockwave .22 caliber [csnp2sx] a nitro piston 1 or nitro piston 2

The NP2 guns are sold with that as a major selling point. If it's not spelled out in big, colorful letters, it's not a 2. The np2 you see is just the model number. Nice rifle, too.

Why won't my Gamo big cat not **** when I fold barrel.

The three reasons that stop a springer cocking are
1 main spring has broken and stopping the piston reaching the trigger sear and engaging . remove spring to check
2 trigger is jammed and not allowing engagement of sear or trigger unit is broken (may be a spring broken easy fix )
3 piston engagement slot damaged broken ( replace piston)

If it is trigger wear problems think about getting it repaired or replaced depending on length of time owned

Gamo cfx royal

Zero the weapon to 30 yards at first then try to get all your shots inside a 40mm circle once you can do that move out 5 yards and repeat until you reach a distance you are happy with like 50 to 60 yards as long as your first shot placement is the kill shot
