Question about gas adjustment on FAL

I just bought my first FAL and I absolutely love it, but I have tried adjusting the gas system and the adjusting ring wouldn't move. After removing the handguards I have found there is a sort of pin holding the adjuster in place (I will include a picture). I know these adjusters were notorious for getting bumped and causing problems, so I'm assuming this is in place to keep that from happening. However, I need to take this rifle to the range and tune the gas system and this pin doesn't seem to want to move. If anyone can help me with this I would be very appreciative. https://photos.app.goo.gl/eH1N5kPwUdF4xVMn8

That is basically a spring that keeps tension on the regulator. You need to soak that regulator in some PB blaster or something like that to get it to rotate. It's probably just stuck from powder fouling. Take a rag or something to grip it with. There is a wrench but I've never found them all that great.

Go ahead an pull the gas plug and piston while your at it and clean your gas system. Plug may tight there as well. Hose all that stuff down. You can't hurt it. Gas regulators will split if you crank down on them too much with a pliers. But they're, to me, a part that I keep a handful around.

The plug was easy to remove and there was not much carbon build-up in it, I am currently letting the regulator soak and I'll try to move it in a couple hours.

Great. Just make sure you turn it completely an entire turn so it is back to the semi mode. The single shot version for grenade launching can trip you up if your new to them. Or even sometimes if you been around them awhile

MB is correct in suggesting a good soak to start. The FAL wrench might do the trick to break it free, or not. I have used M-14 flash suppressor nut pliers with success on stubborn ones the FAL tool wasn't effective on. Good luck.

Yep I've wrapped them with a rag and wiggled with pliers and they started moving. I also said screw it after busting a tooth and took the rag off pulled one out of the bin. That was an Enterprise kit where they parked the entire front end.

You will visually see the gas bleed orifice getting larger or smaller with rotation of the adjuster ring, too.
Easy to tell if it's bleeding off *all or none* (open or closed) looking down onto the regulator/gas tube assemblage.

Just got it loose, just needed to soak and a little bit more leverage.

You might want to Google "FAL manual". All your questions will be answered by reading one!

Soundds like the pin that holds the gas tube is out of place or not fully installed? This will keep the adjuster nut from turning.
