So here's the situation. I was helping an friend clean out her shed. Tools abound. I will mention that she is a widow. Anyway we managed to clear a path and got to the back of the shed. Well there was the 015 that had been sitting for many years. She was going to have a yard sale to clean out the shed and hopefully put a few $$$ in her pocket. Anyway, she asked me it I wanted it, so being a member with an active case of CAD, I took it. To cut through the lard to get to the ham, the saw has great spark, and now it is running. It even oils. The problem I now have inherited is the chain spinning all the time. The clutch bearing is fine. I went to my local Stihl dealer and asked if he could order the clutch spring for the 015. Reply, no longer available. Anyway I figured I would see if anyone could point me in the right direction to locate one. The idle is set so low that the engine will stall if it was set any lower. Anyway the 015 is now resting comfortably besides the 025 and grandpa the 041.Any information on the spring would be helpful. Thanks, Ken
