I just picked up Yugo M59/66 and have heard that they may develop feed problems due to gas escaping from the gas tube near the gas shut-off. I was wondering, has anyone had this problem? How can you fix it if it develops?
:confused:

Most folks find they can restore good function by putting a piece of 20-gauge copper or brass wire at the joint, like an o-ring. This will seal the joint. I simply coated my gas valve (the inside piece) with Blue RTV Gasket Maker, and it has held up through many range sessions (several hundred rounds). I don't expect to use the grenade launcher, but this sealer remains soft and is easily removed.
Some with machining skill have made new valve-bodies to fit snugly in the housing. It's pretty simple to make on a lathe.

The fix depends on how bad the leakage is. Some aren't too bad, others are very corroded.
