Recently decided to check out the internet for replacement chain saw loops, as my little town has limited availability and although I have owned and used chain saw for years, I am a little confused over the many different kinds and types I found out there. My current saw uses a 3/8" pitch, .50 gauge chain. I've found all different kinds out there. Can they all be used on the same saw, or is a different sprocket or bar needed for some as opposed to others - even though they are 3/8" pitch and .50 gauge? Is it possible to use 3/8" and 3/8" low pitch interchangeably? Any help would be appreciated!
