My first gas chain saw purchased in around 1983 after putting in a cast iron Korean Jotul stove knockoff from Simpson Sears in 1980. I used an electric Wen before the Mac, hauling logs home and cutting them up with the Wen. Which I also still have and use quite often. The Mac 330 is an almost constant tinkering with needles and screws. Often it just takes a day off.
I see McCulloch PM 610 saws all the time in running cond for $100 or less. I had one years ago and it was slow cutting, but it always started.
