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.

Personally I went with the Echo PB9010T over the Stihl BR800. Both are great blowers and the Stihl 800 side starter is an awesome feature. Being able to start it without taking it off your back is an awesome feature.

That being said I don’t like the 4 mix engines at all. Had the BR800 been a 2 stroke I would have gotten it over the 9010. Personally I absolutely hate the sound of the 800s 4 stroke engine it drives me nuts. Also there have been issues with the plastic cams in the Stihl 4 mix engines (not a big deal to replace one) but it’s another strike against it in my book. Also the small end of the con rod on the 800 doesn’t have a needle bearing but rather a bushing. I have see a few of those bushing wear out prematurely mostly on commercially used blowers (landscaping companies) that probably had a ton of hours im them.

Anyway they are both good blowers and you will probably be happy with either of them.

The reason was nozzle velocity followed by comfort and weight. The 9010 clearly has more power, but was too much weight and bulk for me. Stihl claims they went with a bushing as a needle bearing would not hold up. Yeah, I know that seems weird, but the piston pin and bushing are huge. At 32 to 1, it should hold up just fine for what ever time I have left. As far as sound, this thing sounds great at full RPM, cant complain there, it rips. And at 4.4HP, it's not down on real world power or RPM.

Like you, I much prefer 2 strokes. It's my thing. Maybe that's why I started this thread. It's way better than expected. Really blasts under the wet leaf mats and rips em loose.
