Hello all,

I got a Cooey model 64 from my grandfather a while back.
Every 8 or so rounds I get a light primer strike.

Does anyone know how I can fix this?
The gun has some sentimental value to me, so I would love to get it working.

Also, the rear iron sight is missing, where could I find a replacement?

Thanks
 
Take it right down and throw it into some solvent for a day or 2. I used gasoline on the last 2 I did last week.
Use copper/stainless steel "tooth" brush's on the carbon built up area's. Slide the firing pin out and look on it for carbon.
Scrub,wipe off/rinse off ,oil and re-assemble.
 
They like to be ran fairly dry as well, I had trouble with my old man's when I oiled it a bit much, cleaned most of the oil off and it was perfect. Western Gun Parts out of Edmonton should have the sight in stock, as well as an elevator, just note they have a $25 minimum order.
 
I adore my 64's!

I got my first one 25+ years ago. It was old then, and still my favorite.

These can be finicky with ammo selection. Pick a round nosed, solid ammo.

Take your gun apart. Get used to doing this every 500-1000 rds. Clean it thoroughly, and oil it only for storage/rust prevention. For use, run it dry. Any lube in the action collects mung, and fouls faster.

Take it down by removing the stock, removing trigger group, and mag well. The barrel is retained by the clip that holds the front of the magazine well. When removing your barrel, do not twist your barrel inside the receiver. A broken ejector will be your reward! I have used the bolt itself to get a barrel moving. The barrel must be removed to get the bolt out. Once apart, scrub it all thoroughly. Brake cleaner works well, and dries quickly. Any solvent will do.

This whole process takes about 15 minutes.

Once you have it thoroughly cleaned reassemble (dry) and have fun. You can "postpone" cleanings by flushing your assembled rifle with brake-cleaner, but it's not a substitute for a good cleaning.

Same rifle in production for 50+ years means something.
 
Yes, remove the guts and give it a thorough cleaning. But for God's sake DON'T USE GASOLINE! That's just, well, let's say less than prudent. There are plenty of other solvents which are far, far safer and equally effective. A homemade mixture of Ed's Red works great. Ensure the extractor also moves freely, otherwise it will contribute to feeding failures.

As for shooting, yes, if you have no lubrication it will accumulate less carbon buildup than if you use a traditional oil. But if you use a newer synthetic which doesn't cook and turn to baked grunk, it will operate longer and stay cleaner. Carbon won't bake onto the metal surfaces to any significant degree. Something like BreakFree CLP, try it, you'll see.
 
The insides of the gun were filthy when I got it, full of sand or something.
I wiped it all out pretty good, but I never cleaned it with solvents or anything like that.

I guess I will try that next, thanks for the advice!

Cheap, easy to use and completely safe when proper percaution's are used.
I want to de-grease,not lube.
What do you use in your Ed's red?
 
Ed's Red is four equal parts of auto trans fluid, varsol, kerosene, and acetone (optional). Recipe is all over the internet, for more details. (Although acetone is flammable, it has, however very high ignition initiation energy point, so accidental ignition is rare. Even pouring or spraying acetone over red-glowing coal will not ignite it, due to the high concentration of vapour and the cooling effect of evaporation of the liquid.)

Gasoline is highly volatile. It's vapours are much heavier than air and will settle. Gasoline fumes are toxic. It is highly flammable, easily ignitable and explosive. There is NO reason to EVER use gasoline for cleaning, no matter how careful you think you are. It is not 'completely safe' in any sense of the meaning. If you wish to risk your life by using it, go ahead. But do not tell others to use it.
