Best Answer

It depends on the elevation you are running.. lower elevation= dence air. Factory settings are 2 1/2 turns out. Start from there and go for a run take your sparkplug out and check the color... If its white then you are running too lean turn it 1/2 turn out until you run it and its brown in color. If you take the sparkplug out and its wet you are too rich. Turn it in 1/2 a turn until brown. If you are asking about what ratio to mix 2 cycle fuel then if you are using a synthetic oil its 40:1 regular oil is 32:1
