Right on Racer. I run 50:1 on mine with Amsoil Saber and non oxy. This is a bushing motor. On needle bearings as well as all my chain saws I run 2 oz. per gallon.....64 :1. Haven't burned up an outboard or saw in 40 years. Got 041 AV my very first saw.....cut 100's of cords of oak......right here to prove it.....want a video? Raquel and Tim's Timber Duluth MN since 2000. Before that Tim's Firewood and Repair.....since 1973.
Run a ms 880, 660, 064, Homelite 925 xl, 410, 90 Jonserud, and big Olympics, smaller saws include some Huskys and Partners. Going for high torque lower rpm as you can see......I'm a "chainsaw guy". The John Deere CS 81 is actually an Italian made Olympyc. 81cc. Beauty of a saw. Also have a Philippines 08 Stihl......German powerhead surrounded by China plastic. Over 100 CC's......brutal powerhouse, best used for ripping lumber......heavy but big power. Designed for ripping.
