GR LINE SAW - What is this?

[RoncaliVineyard]

I was at my Grandpa's house this weekend and he told me he had an old saw. I told him that I would like to look at it. He said that he never even tried to fire it up but it had a good chain and bar on it. It was an GR LINE 123. I looked at it and it seemed like it had a model airplane engine that ran it. The carburetor is smaller than my little finger. Gear reduction drive without a clutch. Strange. I pulled on it and it has tons of compression. What type of fuel should I attempt to burn in it? Anyways, if someone knows anything about this saw I would be happy to know what you know. I looked online and couldn't find any information on it.



Here are some pictures of it.<br><br><a href="http://s45.photobucket.com/albums/f63/jancagle/?action=view&current=IMGP4827.jpg" target="_blank"><img src="http://i45.photobucket.com/albums/f63/jancagle/IMGP4827.jpg" border="0" alt="Photobucket"></a><br><br><a href="http://s45.photobucket.com/albums/f63/jancagle/?action=view&current=IMGP4828.jpg" target="_blank"><img src="http://i45.photobucket.com/albums/f63/jancagle/IMGP4828.jpg" border="0" alt="Photobucket"></a><br><br><a href="http://s45.photobucket.com/albums/f63/jancagle/?action=view&current=IMGP4829.jpg" target="_blank"><img src="http://i45.photobucket.com/albums/f63/jancagle/IMGP4829.jpg" border="0" alt="Photobucket"></a><br><br><a href="http://s45.photobucket.com/albums/f63/jancagle/?action=view&current=IMGP4831.jpg" target="_blank"><img src="http://i45.photobucket.com/albums/f63/jancagle/IMGP4831.jpg" border="0" alt="Photobucket"></a><br><br><a href="http://s45.photobucket.com/albums/f63/jancagle/?action=view&current=IMGP4832.jpg" target="_blank"><img src="http://i45.photobucket.com/albums/f63/jancagle/IMGP4832.jpg" border="0" alt="Photobucket"></a><br><br><a href="http://s45.photobucket.com/albums/f63/jancagle/?action=view&current=IMGP4833.jpg" target="_blank"><img src="http://i45.photobucket.com/albums/f63/jancagle/IMGP4833.jpg" border="0" alt="Photobucket"></a><br><br>

That's an Orline, not GR Line, they had Cox airplane engines, 21cc I think.
Here's some info on a similar model saw. http://www.acresinternet.com/cscc.n...e426ce44969dee3f88256e49006914e9?OpenDocument
They show up on Ebay quite frequently. CSW

It looked like a G.

Sorry it looked like a G, not an O. Thanks for the clarification.

Those old O&R carbs really suck and are real hard to get parts for.

Never did find parts for mine.Had a good friend make me a diaphragm and gasket set.

A fun little trim saw to run.Has a sound all it's own,especially if you uncap the exhaust.

Yeah I hate my ears...........

So wait!? What does it run on?....Nitro?! That sucker must really crackle!

There are several models of small chainsaws which used the Ohlsson & Rice engines. Some are called O&R, others Orline... they even made one colored blue and badged Ford which Ford dealers used as a promotional item to give to buyers of new cars and trucks.
Ohlsson & Rice also made engines for radio-controlled model airplanes and model race cars and some slightly larger ones for powering roller skates, bicycles, generators, and a bunch of other devices.
Cox, too, made small engines for both RC model airplanes and two models of small chainsaws... but Cox was a different company and their chainsaws look very different from the O&R and Orline saws.
I have a few of the O&R and Orline chainsaws... and both models of the Cox... and I just bought a week ago two O&R engines totally disassembled.

I'd be interested in your grandfather's saw, RoncaliVineyard, depending on what you want for it. Send me a PM with your asking price and I'll get back to you.

A Cox-powered chainsaw? Sounds really cool, if a bit less than practical...
Can you start it by spinning the propeller, or maybe just pulling on the chain?
(just kidding, really, jest pulling your chain, hahahaha)

It is a neat looking old saw. I like the NPT exhaust pipe....nice touch.

Seems like the one I have has a direct connection from the throttle to the oil pump. Every time you blip it, you get a shot of oil to the chain - very messy!

Back in the middle 70's I worked in a lawnmower and chainsaw shop. I worked on a hedgetrimmer and a water pump that had the O&R engines. They always seemed a bit weird to me and they were so small and light I couldn't imagine they would be durable.
