The problem I found was that sometimes when cocking the bolt handle the bolt wouldn't cock. Sometimes, more significantly, the bolt when cocked would fire with little to no pressure on the trigger. I took it to someone who advertised himself as a gunsmith and he charged me a fee and claimed to have fixed it. Well..... not fixed actually. I put the gun away until the other day, several years later, the rifle and the problem came to mind.
I found what I thought was the problem discussed with a Google search. The problem was caused....said the online palaver... was that the sear wasn't locking into the groove on the underside of the bolt. Said cause was that the soft steel sear was being worn down and not locking in because of rough and frequent use. This was happening on the chiseled front end according to some and on the rounded side top edge according to others.
I found a diagram of parts online and proceeded to take the receiver apart. I also looked online for replacement parts and found some sear/trigger assemblies. But I wanted to have a close look at what I had first before ordering anything. However, after taking the receiver apart, the sear didn't look look at all buggered. I did notice the trigger spring was gummed up with grease, although the spring still seemed strong, and I cleaned it up. I put all the parts all back together again.....lot harder than taking the them apart of course. By the way, the hardest part was getting the trigger pin to punch out and go back in, even though I had some gunsmith punches I bought years ago.
When it was all back together successfully the same problems were evident. Then.... I tried keeping pressure on the trigger pushing forward through the cycle of cock and shoot. No failure to cock, although the trigger pressure to fire was still less than it should be. The spring, although seeming to be strong wasn't....or the plunger part that went into the spring was some how bent or compromised. At least that's where I'm at now. Just have to get parts 70 and 71 in the diagram to see how this works.

You can't fix Stupid, but you can occasionally head it off before it hurts something.
It wasn't hard to take apart. It was a pain in the butt to get several of the pieces all in line to put a couple of screws through in reassembly though.
The largest problem to start with was that the parts I was sent only looked sort of like the parts that were in the gun. The spring sent was shorter the metal bar that linked with the safety was shorter. In the end I put the old spring and safety link back in the rifle. However, after much fiddling and observing what was happening I came to the conclusion that the reason the cocking of the bolt sometimes doesn't lock isn't the safety spring. I'm beginning to think it is wear to the sear, although visual inspection in inconclusive.
It did give me a chance to play with my new gun tools though.

Then I spent the next three or so hours alternately trying to get all of the part holes lined up and looking for the trigger spring that popped out regularly. Finally.... all together.
Result..... same problem as before. I put the rifle away for another day and another chance at guessing what is wrong with something with as few parts as this thing has. It has to be something simple wrong that needs correcting but I don't know what. I'll try it again next time there is a rainy day and there is absolutely nothing I have to do. Maybe the problem is in the bolt itself....although I can't imagine how that could be.

For some reason I just can't set it aside like it has beaten me. Yes, that sounds stupid, but maybe it was
all those years of having to make sure it works on the job. Production machinery had to be fixed right now.
Or maybe I am a little OCD, but "Fix it or Fuck It", if it can't be fixed throw it away and get another one.
