I have a beautiful like new Yugo SKS that will not cycle rounds properly.
I have narrowed it down to the gas system, here is what I have found.
1) I bought a $0.75 rubber O-ring at autozone and fitted it in between the gas tube and the gas valve. The rifle cycled flawlessly for about 20 rounds until the O-ring blew off from the pressure and heat. Because of this I know the issue is the gas system and not something else.
2) The gas port is not blocked in any way by carbon buildup or corrosion, and the rifle is not set to the blank firing / grenade launcher mode. It also appears that the handguard wood is a different color from the rest of the stock, leading me to believe that the gas tube was not the rifle's original one.
3) I recently purchased a new stainless gas valve and installed it. The rifle will still not cycle properly, and I do not want to keep having to put a new O-ring on every 20 rounds or so to keep this rifle going.
Before I spend more money buying parts that might not fix this issue, what is the likely cause? The only other options I really see are a new gas tube or new gas piston, but I don't want to drop $50-$100 on parts that possibly don't need to get replaced. I also want to keep the rifle as close to original spec/appearance as possible, no tacticool bubba BS.
