My choice, Stihl 800x backpack blower.

I went down to the VP Racing gas station and purchased 6 gal of C9 (now 97 octane, love the stuff as it simply runs great) and VP's two stroke oil. Prob mix it with C9 at 32 to 1 just like everything else. It will be interesting to see how it compares to Motomix that's in it now. I've used up most of the tank of Motomix and the blower has broken in nicely, even more RPM than when brand new. Awesome!

As far as semi self supercharged, the 4 mix engine uses crankcase pressure to push air/fuel into the intake.

If you don't mind sharing what are you paying for the C9 Racing Gas in 6 gallon quantity? do you bring your gas can or is it pre-packaged in different volume steel can container. I might have to give it a try.

I am currently buying 89 REC Fuel for about a $1.00 to $1.50 over the 87 (R+M) 10 percent ethanol unleaded. So depending which state I am in when I buy it is is between $4.60 to $5.50 per gallon lately.

Since I have been use REC 89 with VP Racing 2 stroke oil (ratios of 45:1 or 40:1) I have never seen any exhaust port or spark arrestor screen carboned up. I had to replace a head gasket on my 20 plus year old redmax handheld blower a few years ago and piston/rings and internals looked very clean (used Redmax oil before VP Racing)

Thanks
