Yep could'nt beleive it at 1 & 1/2 turns out the thing was still sittin at 13,400. At 1 3/4 the idle would'nt controll itself fast enough to stop the chain even going after the idle speed screw. It has a good amount of grunt & the 8 pin makes up for what little bit of rpm its missing. Dont see it having any problem running a 9 pin in soft wood , it does require adding 1 extra link to do it then you cant run a 7 pin. You probably could run a 18" or 20 " bar with the 9 pin if you used skip chain. & that being around 110 " per second instead of 90' with the 7 pin.So your hi speed needle is at 2 turns out you say.......

several years ago I returned home from work late and wanted to get the yard mowed b4 dark. out of mower gas and no time to run to town and still mow b4 dark.
filled up with race gas as it was all I had at the moment( don't remember the exact octane but it was Unacal racing gas )
noticed the mower didn't bog down as much in the thicker parts of the lawn as usual
normally used a tank and a half to do the whole lawn, this time mowed all on just under one tank full
I really don't think my 5.5 hp briggs is a "high compression" engine
now maybe I'm just looking at this all wrong but it sure seemed to me that I completed the same task on less fuel and the mower did not work as hard in the taller grass
but I guess this would have nothing to do with how a chainsaw would run on better fuel huh?
You run whatever you wish...I'll stick to the good stuff
Steve here... I ran it(race car gas) in my John Deere 425 garden tractor... 2cyl watercooled Kawi. The engine missed from time to time. Put regular in it and it was fine again...

the point of higher octane gas is to prevent detonanion.
As I tell most people on all these pointless subjects... You use what you want and I'll use what I want. Some people have run 104 and had a saw last for 20 years! And I've used pump gas and had the same. Point of the whole thing is... At least use some good 89+ octane fuel and good quality oil from whatever maker you want and you'll have some great fun use of your saws or whatever. 89 octane doesn't cost an arm and a leg so no problem with that. Enjoy.
