Any chainsaw / firewood cutting experts on here?

The biggest thing is to run a quality fuel. Long as you do that, a damned dollar store chain saw will hold up. It's the ethanol that kills them. I had a 025 Stihl for a long time. Probably 15 years. Used it heavily around here. Burned up the crank bearings in it. Wore that thing slap out. It was a good saw. Think I paid like 250 for it back then. It was a good saw. Came with a 16" blade and I upgraded it to an 18". It cut good.......till it quit.
