I feel that one should always err on the side of caution when it comes to lubrication, I run 40:1and when it gets buggy in the woods I'll dribble a bit extra in to generate a smokescreen.Jaoneill do you run 50:1 in your Jreds?
That will help as well.....I'll have to make the switch, that 20" bar runs a .050 chain instead of the .058 too. Not sure if that makes any difference in cutting but I've never run that before.
