My advice - if you are not mechanically inclined - don't!
The BL-22 is one of the more challenging guns to reassemble.
If you do take it apart - take digital photos of the action and it's assembly every step of the way and make notes on how the parts fit together.
If i remember correctly you have to use a blind pin to keep the carrier spring in place during reassembly. You also have to make sure the carrier spring is installed the correct way.
Yup, i took a browning lever action 22 apart at deer camp and it too me about an hour of tinkering to get the whole thing to fit together and work.
You were extremely lucky. If I remember correctly there is at least one spring that has to be held in with an assembly pin. That one is an absolute b*tch to keep in place without the assembly pin.
