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

The VP Fuels station has C9 right at the pump, even has a CC reader. $12.50/gal. Bad, but not $26/gal bad if purchased in a 5gal pail. Sadly, it was $8/gal not long ago. I love the stuff. Runs clean, consistent and very low carbon buildup. In a direct comparison with 90 octane zero ethanol fuel, Mobil 1 MX2t both mixed at 32 to 1, the C9 runs about 3-500 RPM higher in my Stihl BG86 blower. It's kind of hard to get my Hazard Fraught Tools optical tach to read the impeller. But there is no question the Rec fuel falls short, regardless of how I adjust the carb.

VP makes some non ethanol, buy oxygenated fuels that flat out rip in chainsaws and blowers. I've had great results with T4+ (yes it's designed for 4 strokes) in my two strokes. As it atomizes well in the crankcase and reduces blubbering and 4 stroking to an absolute minimum. Just crisp, clean sharp operation and a bit more power than C9.
