OK...my 2¢ worth...running the saw with a 32:1 oil ratio means the saw is getting less gas...
So it's running 'lean'..as in Waay too lean and the AutoTune just couldn't correct the Waay to lean condition...
Sooo...1 scored piston!! - I just don't understand why soo much oil in the fuel..??
I run Amsoil Saber at 50:1..and Stihl orange dino at ~ 40 or 45:1 - - I've never scored a piston in my long life..!!
I just don't understand why anyone would run 32:1 mix in a 'modern' saw..??
Or run 100:1 Amsoil - There is
Nothing on the Amsoil label that
Recommends 100:1...just that it
Could be run at 100:1
