I've been working on an XL-76 chainsaw I was given out of the blue a little while back.
After a little research I found it was built in Quebec as a Canadian version of the XL-123. I found a place in Ottawa I could get a few parts for it. They were VERY happy to sell me the fuel line and sprocket as they'd been sitting on the shelf for years, lol.
When it was given to me I had no info on the thing. The bar chain and sprocket were well past worn. The saw was covered in sawdust and oil.
I've had it completely apart and back together now. This is what it looked like half cleaned.
had to replace the fuel line and scrape the massive amount of carbon out of the exhaust port.
The flywheel was nicked by one of the pawls, which would then hang up on the flywheel. I took it to work and had one of the welders zip that wing back up so I could grind it down - can't even tell it was repaired now ;D
The kill switch lock nut was missing, so I got a nice new ring and on/off plate. However, I can't seem to get the saw running with the switch hooked up.
Using an ohmmeter I measured a measly 2 ohm resistance switched on and 0 switched off.
Is this normal? I would have thought infinite resistance would be much more appropriate. With the switch out of the loop the saw started up pretty decent! Actually, I had left the muffler off thinking it wouldn't be much louder than the weedwacker I just repaired.. I nearly had a coronary in my little garage.
It currently runs (without the switch) and starts with a little shot of moovit down the neck.
However, it idles real high, doesn't rev, is a pig to start and seems to blow fuel out the exhaust AND the carb box.
I think my next step will be to take the carb back off and check the metering lever and reed valves real close. The reed valves looked very nice but you never know.. this IS my first chainsaw rebuild
I am a mechanic by trade, just getting into small engines this year!
I have lots more pictures to come and maybe a movie or two.
Thanks for reading!

and it starts very quickly! I'll post a video soon but for now, some new pics with a camera I'm trying out.
