FX Royale 400 .22 cal no air when firing rifle

I double checked valve, every item seems to be in order. I double checked barrel transfer port, its good also. The regulator rebuild I Replaced the following:

2 outside o rings

3 inside o rings I did not disassemble the Belleville washers or removed the locking distance nut

1 plastic plug

When I pull the trigger, there’s no resistance!






Sounds like its not cocking, sear is in correctly on the rear most pin?
