I used to own an XL-76, and that thin was a real pain in the Arse. Hot or cold it was a real pain to get it started. I even replaced the Points and Condenser, put in a new Carburetor Repair Kit, made No Difference.
I have a Mac 10-10 Automatic, that my Great Uncle Bought new in 1968, Forty Years ago. It used to have a the Starter on the Right Hand Side. It used to be a hard starting Saw, until I noticed that the Magneto was not square with the Fly Wheel. I adjusted it so that the top and bottom parts of the Magneto, are 0.010" from the Magnets of the Fly Wheel. There was only 2 other problems I had with the 10-01. One was my fault, I didn't get the Clutch tightened properly, and the Clutch came loose, and wobbled on the Shaft, chewing out the Key Way in the Crank Shaft.
instead of getting it fixed, I had a Fly Wheel, and a Starter for the Left Hans Side, and just switched it over. I also had a Chain Brake, so I put it on as well.
The other problem, I had was that the Treads for the Spark Plug got worn, and it blew out the Spark Plug. I got an adapter kit to restore threads for Spark Plugs, and installed the piece, put in a New Spark Plug, and it's back in my every day line up.
Great handling Chain Saw. I love it. The Homelite XL-76 couldn't even come close to the 10-10. That XL-76 Soured me on Homelites. Bruce.
