    what fuel mix ratio?

    Ok, I have a 500 Super Chief. What mix ratio is everyone using on there attex. The manual said 20-1 but is this what most people are running. Ive been told make it 50-1 or 32-1. Just looking to get a better idea from fellow Attex owners.

    If you're using petroleum based oil, you should stick with around 20:1 but with a good synthetic lube you can go 40:1 or 50:1.
    Stuck in the seventies- not in the swamp.

    (6) Attex, a Hustler, a Super Swamp Fox, (2) Tricarts, (3) Tri-sports, a Sno-co trike, 3 Dunecycles, and a Starcraft! ...so far

    Only had it for a couple weeks now. Bought it and doing a fuel tank flush, tune up and an UNI air filter. The tank had dirt in it and the former owner wasn't running a fuel filter. I run RedLine 2 stroke oil in my quads and bikes. I plan on running RedLine in the Attex as well. Anyone use RedLine here? And what mix ratio?

    I run Blenzal (like the way it smells) and Redline when I can find it in my dirtbike YZ250 40:1 .
    In my Attex 400 I have been mixing 20:1 just to be safe since I am just learning about these machines. Its smokes some but runs great and plugs look fine. If it didnt smoke I would be worried.

    I would like to make a Uni filter fit, did you make a flange for it? Mine has the flat 3-bolt Walbro mount

    so Redline 20-1 should be fine then? I was just thinking of buying a UNI that clamps on the carb.
