The third Cox Beaver chainsaw.......with a surprise

Admin wrote:Good alternate use for existing Cox parts. I wonder if this saw is an early version or a late version.

Aside from the obvious difference between the "Beaver" and "140" label, there appears to be quite a bit of variance with these saws. Plastic carbs, metal carbs, oil/gas tanks positioned on different sides, different patterns on the handles... all for something that was only made for a relatively short amount of time.

Thanks Jacob, but you're seeing something that I am not.  

All my chainsaws have the fuel tank on the left hand side as well as all I have seen except in this picture where it's on the right.



I think maybe the caps were swapped?  Either way there is identification cast into the tank designating which is which.

Cleaned the engine externally in Berryman's then opened it up.  Cleanest of the three.  





Then cleaned the interior in 91%.  Watch it get progressively nastier.










No need for fine steel wool or any abrasive cleaner on the shafts. Best low time engine so far.

I should've linked to this: http://www.chainsawcollectors.se/phpbb3/viewtopic.php?t=873

That's where I noted several of the differences from. I stumbled across that while trying to look for a good shot of the "Beaver" label for Levent.

Thanks for that link Jacob, I was on that site but missed that post.  Bookmarked it.

Telling picture:



Sent me looking at mine which all have the extented basket weave pattern.  

Mine all have the fuel tank located on the left and are cast Fuel and Chain oil into the tanks.  Pretty strange that Cox changed them around.



Discussion about these go back a long way here on the forum, back to 2012 long before I became a member.  People I do not know.

These gas/chain oil meters do not show on the parts diagram or parts lists and between my three chainsaws are not universal.  Some chain oilers are automatic, others use a press a bulb to lube the chain.  These are curious.  The star reed must vibrate from a vaccum provided by the engine to pump the oil to the chain.  

The reason I noticed the reed on this meter was because the membrane was missing.



The meter snaps on to this device which is connected to the engine through a tube in the handle.




Stayed up last night and sandblasted the bar and soaked the chain in Berryman's and assembled one of the two chainsaws.  Both were missing some parts so I borrowed parts from one to make the other complete.  



What's left.  I will need a carburator (forget it) points and condenser and bar and chain to complete.

Thanks George, I'm thinking a bit smaller, perhaps .020.  When I get my courage up I'm going to remove it to see.  I'm sure the gas meter is the same, using a reed and crankcase vacuum to pump gas to the carburator.  

I'm having no luck finding a vintage carburator, searched everything.  But I did find a bar and chain with the correct pitch and rail width new on ebay @ $8.49 shipped.  Cheap enough.  To get those specs I had to get a 14'" bar and chain though.  It came with a 12".

Reassembled the last chainsaw.  Spare parts, all accounted for except that copper head gasket.  One had a single gasket, the other two.  Forgot which one.    Maybe my pictures will help me.




Edit:

What do you think?  Remove the flywheel drive, add a blanking plate and a glow plug adapter.............. 14" Prop

You'll probably have to set an eBay search watch for the carb and wait for one to be listed. Might take a year or two or three before one comes up.

In the meantime, I wonder if you or someone on here could fabricate an adapter plate to allow a Walbro, Tillotson or similar small engine carb to be mounted and used.

I'm open to most anything Jacob, but the carburator is just one piece of the puzzle.  I would also need points and condenser and..........at least one maybe two of those little Cox reed-valve pumps.  Somehow chain lube oil and fuel has to be pumped up to those features.  Gravity would not do it.

They do run, and run well.  Got a nice little bark to them:

Oh boy, number 4!

I do not want to be caught up with Cox chainsaw's but I could not pass this one up. Complete except for the carburator air filter. Has both Cox style metering pumps and the fuel tank is on the opposite side from my others. And, cheap with only four bidders, mostly chainsaw collectors, no Cox folks. Disappointed in you Cox Engine Forum guys.

I knew you were probably going for it, so I didn't bid .



Hopefully this one is complete this time. No hidden missing parts.

Absolved.

This seller does have some interesting Lawn Boys, but shipping is a killer and he's over-priced on most everything including his two Cox chainsaws.

That bricktop has something going on with the weld repairs on that handle. I also see it has a damaged magnesium deck. Unless there's something special and rare about it, or you intend to use the engine or parts off it, or its cheap or free on the side of the road, I'd avoid the ones with severely cracked or chipped magnesium decks.

What you probably want to do is try to find one locally on Craigslist or Facebook Marketplace.

It's actually not uncommon to find someone with a large pile of Lawn-Boys out this way:

Wow, Lawnboy heaven Jacob.

I would think that trash collectors would toss them aside and sell them later perhaps on the internet. Free stuff and all profit.

Bob, have at, we wouldn't want to spoil your fun.

However on other things, I keep vewy quiet then show up with what I won.

My routine too George.  Coming from California, shipping is pretty heavy and I hope that he sends it FedEx or UPS.  Although USPS shipped me a bunch of model train stuff today that arrived quickly and undamaged.  

But my day was taken up with this:







Chain saw residue................thankfully my son came over and helped.  I will sleep well tonight.

Looked like this not to long ago.
