Thanks for posting the great information on your 7900. I live in central MA & just bought a 7900 myself. The saw came set up with a 22" winsor speed tip bar & chain. Man this saw is a screamer!! Anyway I was just curious what ratio fuel mixture you run in your saw. I was told 50:1 would be fine with a good quality oil. What bar & chain oil do you run? I have always run amsoil synthetic in all my equipment with no problems. What do you run for premix oil? Any recommendatios would be appreciated!
Thanks,
Eric
