    Comments

    If using a different brand of oil other than Klotz, OS recommends
    their own mix ratio which may differ from the manufacturers'
    For 40:1, and 50:1 oils, OS recommends a 30:1 gas/oil mixture
    25:1 is 5oz of pre-mixed 2-cycle oil or 151 ml per gallon of fuel
    30:1 is 4.3oz of pre-mixed 2-cycle oil or 126 ml per gallon of fuel
    40:1 is 3.2oz of pre-mix 2-cycle oil or 95 ml per gallon of fuel
    50:1 is 2.6oz of pre-mix 2-cycle oil or 76 mll per gallon of fuel

    The following mufflers are ideal for different applications;
    J'TEC Large Wraparound Pitts Muffler for inverted
    mounting applications.
    Bisson Wraparound, and Inverted mufflers will also fit
