Ryboi 790r


Thank you for your question.

I can understand wanting to know the correct fuel mixture.

The mixture should be listed on the fuel cap.

The correct mixture is 40:1, which is 3.2 oz. of a quality 2 cycle oil to 1 gallon of gas.

If this is a brand new model it would be 50:1.

I hope this will help.

Thank you for using Manage My Life.
