Heviarti my 797 starts really easy with 100LL in the cold. Just have to give it 4-5 squirts with the carb primer. It fires on first or second pull with compression release...released. When things are warmer only 2-3 squirts. It also starts about as easy on pump gas. I run Mobil pump gas simply because the Mobil filling station we have here has a separate distributer & tank for each grade. Doesn't mix like the rest of the brands including Sunoco. But this is THIS particular gas station. Other places will have other brands where that is true. I don't like buying fuel for my sawswhere they have the same hose for different octanes. When I'm filling something as small as a five gallon can, the volumn of fuel in the hose from the LAST sale has some impact on my final mix. What if the last sale was 87 octane? And I wanted 93? By the way all the AV Gas I have purchased came from Accent Technology, a Phillips company. They also sell a 87 Octane "Mo-Gas". But as was mentioned in this thread, they all pull from one of three terminals up in my part of the world. One in Albany, Rochester, and Syracuse. If you want Alcohol enhanced fuel only the Rochester terminal can provide that. I wouldn't put that garbage in a plane or saw.
