Happy with how it pulls 42"square skip threw hardwoods slicing all the way. Big tree service crews- sub contracted to city, think I'm going fast with a chain that needs a touch-up while the power-head sings cutting a full 38" across
. Same fuel in ms-460 got me started with the skip on 50" & 60" milling sets. Got semi-skip for the 661 which I still need to touch up with the file to better what the factory sends out.
The only non corn is 97 octane unless I head over to Mississippi for higher cost/gallon boat fuel.
Evansaw: I use more oil because of milling stress on internals that are constant/longer time, no other reason. If I was cross cutting intermittant 50:1 is what I'd use even with the "better" cylinder
