You can only do so much troubleshooting without test firing your firearm with live rounds.
If you are concerned with people seeing you firing a potentially defective firearm, it's easy, ep. since you life in B.C. Drive out somewhere on crown land & try it with nobody around for a ways. Enjoy your SKS
Edit: maybe some clearance problems between the wood & your trigger group (unlikely, but it could happen).
This is going to be a three handed operation, because you have to hold the trigger back, depresss the holding opening device, and let the bolt and carrier go forward, but there is not much danger of the carrier slamming forward & hurting your fingers (this can happen with a Swedish AG42/b rifle), but you have an SKS, so no worries there.
