The Beaver chainsaw, Cox's most interesting product

The second one arrived today. If I thought the first was well boxed, well this fellow went overboard. The Mona Lisa should be shipped as well. Double wrapped with instructions.




Always exciting to see whats missing and what has been messed with. Some heat on the flywheel, a cloth buffer and a tap with a substantial hammer and drop the engine onto a soft place.



Ah, points. That and a carburator we are most of the way home.




Most Cox engines are numbered, some are not. This one is. Motor mostly locked up, but I'm not forcing it. Complete disassembly next. I love this stuff.

Hey guys,all this reminds me of my childhood in the late 60s. My dad built me and my brother a 16"solid tire bike.i don't think it was the chainsaw version,I think it had a tickler on bottom of carb for priming and a red rubber kill switch.very fun as a young kid,got burnt many times on that little bugger

Yes, red kill switch. Check where the spark plug lead comes out from the saws body. Press to stop.

I got around to tearing down the most likey salvagable parts chainsaw.  Disappointing surprises.  One of the reeds is missing, might as well be both of them.  No workie without two.  Lone reed visable far left.  



Second surprise is the way the handle attaches. (Above picture) - On this one it looks like it's attached only by a press fit on posts.  All the others are attached by nuts and bolts.




More disappointments.  The PO broke off the fuel tubing nipple on the carburator and tried a brass fitting fix.  I wish that novices would just leave things they know nothing about alone.  A little heat on the tubing and it would have just popped off with a screwdriver pry on the open end.  

PO ..........Well lets see.........I'll just pull it straight off.......Duh??? Well maybe a little side-to side motion..........PO "Oh, Oh"..... Upsets me because this is otherwise a workable and very rare carburator that some dolt ruined. Whoops...Bob is venting.



and...........this PO just could not win.  He stripped the torx fitting on the chain drives clutch.  Again.  I bet that he used no heat when he tried to unscrew it.  Been there on others.  I have to drill some out and pry it off.  Thankfully I have replacements for those specialized screws.  




Chainsaws, around here not just another pretty face.

Yesterday.




Last Spring





They get worked to the tune of many replacement chains.  Sometimes we get them resharpened at $5 each.  But new Chinese chains which last much longer than those resharpened are available on-line @ two for $20 shipped.

Bob, I enjoy your comments, telling it like it is.

A previous owner adds new meaning to why a plumber in town has a slogan on the back of his tool truck, "We fix your husband's plumbing repairs."

The value of experiential knowledge is gained through age and experience, plus a knack for working on things.

I've got a K&B .35 Torpedo bought used with a hacked off piston skirt very poorly done to create SPI, but gap is extreme and very roughly done.

Ruined a good engine otherwise.

I have it's McCoy look-a-like George. I bought it years ago for next to nothing as it was a castor locked mess. But it had a curious glow plug extension that caught my eye.



Today I found another on ebay for way to much money with another curious extension. Not a customer.



I may be able to save that carburator. The PO's brass replacement tube is threaded and a SO square drive screws it in. I think a little Blue Lock-tite or JB Weld on the threads may fix it. PO just smeared some type of cement around it that just flipped off. A 20 minute soak in Berrymans cleaned it up and everything else seems Ok.
