sks wont cycle

[edgeman]

I have to cycle every round manually
torn it down and cleaned it still doesn't work
is this a gas tube problem? it does seem kind of loose

 

[tiriaq]

Is the gas piston free to move in the cylinder?
Is the tappet piston free to move?
Was the rifle working properly, and then stopped?
Does the bolt carrier move at all?

 

[edgeman]

bolt carrier moves
pistons all move
gun worked fine before its been sitting for year now it doesn't work

I'm no SKS expert but I've heard people disable some part of the gas system to make the rifle a single shot bolt action. Is that spring in the gas piston assembly missing?

 

[sigrunes]

Might be a gas tube leak , an o ring or washer might might help seal if so.

Also make sure your recoil spring is in properly and not in backwards. And that it is properly orientated against back of dust cover inside.

 

[edgeman]

the spring is there
im going to try a brass washer
I saw a bit of smoke coming out where the gas tube connects to the rear sight

what does a new gas tube cost for a Chinese sks
not much I hope I bought the thing brand new for $75

I need a parts gun. Sell it to me.

Could it be that the gas port would be blocked, clogged?

 

[mattcwc]

Buy a new one.

is the squiggly side, or the straight side of your recoil spring forward?

Read posts #6 and #7 of this thread.

Check your gas port, try break cleaner ( non clorinated in it ), check your whole gas system and re clean it. Make sure the spring in there is sill ok.

Do you oil the gas system? IF so maybe your gunking it up.

Yep either the little exhaust port or the small port coming from the bore! Pipe cleaners work well!

piston in backwards? port shouldn't be blocked. there would be enough preasure to blow anything out

Lots of things to check over. Because it has been sitting for a year and maybe, just maybe, you didn't clean it really well when you put it away?
