Any chainsaw / firewood cutting experts on here?

I agree with JDMopar. I bought a Stihl Farm Boss too in about 1992-1993. If it ever quits, I'll buy another Stihl. It has a 18in bar on it and I've never met a tree it wouldn't cut. I burned wood for many years. You really need to know what you're doing and never get too comfortable with a saw. Always pay attention.
BACK WHEN WE HAD THE BIG ICE STORM, I bought a big husky, that thing would start the first pull every time , but when it derailed the chain (very often) it chewed the drive sprocket up and the back teeth on the chain. I had three chains so I could change them , instead of stopping to file the burrs off when I was using the dam thing. When I tried to buy a new bar for it , there was no bar and sprocket available for it , nothing husky sold would fit it , luckily the stores took the unusable stuff back. I bought a stihl and have been using it every since.
Back when I was a teenager . we used a 18" homelite , all metal before the plastic stuff came out. We heated solely with wood back then , the fireplace was made wrong and would eat an entire "big" blackjack every 24 hrs. , we used a tremendous amount of wood every winter. That homelite was one of the best saws I ever used , much like the stihl now. .
