They told me that the saws were starved for oil in the mix, and that I have damaged the pistons and the cylinders by running too lean. New pistons can be purchased for these old-timers, but new cylinder heads cannot. So I am done.
I checked the 2 stroke oil the shop had recommended I use. It came with a convenient measure for 1 US gallon / 4.5 litres. Unfortunately the measure was 100:1!! So no wonder. I can't understand why the manufacturer would recommend 100:1, and why the chainsaw shop would suggest that brand to me. I also can't understand why I didn't read the fine print on the oil containers more carefully!
Luckily, I hit the jackpot. A guy I know from a chainsaw milling forum that I participate in turned me on to a fellow in Victoria who was selling four older (not as old as mine though) Husky saws, two 3120's that are larger than the 2100, and two 390's that are slightly smaller. Plus he had a couple 'parts saws', and a ton of accessories, including bars, chain, mufflers, air filters, etc. In fact he was a very nice retired logger who had done a lot of milling at the end of his logging career. They have seen some use, but looked to be in good shape, better than my old saws were. A quick day trip to sunny Victoria via ferry and I came home with my car loaded with the loot.I'll go through it over the next week.

In other news, I pulled a load of wood out of my kiln this week. Pictured is a piece of 'fiddleback catalpa' that was in there. Who knew that catalpa had fiddleback? Who even knew there was catalpa?! This chainsaw milling gig sure turns up some quirky stuff!
