    If he uses Lawn-Boy oil, the ratio is 32:1. One 8 ounce can to 2 gallons of gas. Other good name brand 2 cycle oils like Stihl, echo etc. will work too. There ratios may be a little higher. Lawn-Boy oil is a low ash oil & will prevent some of the carbon buildup in the exhaust ports. Remember fuel starts to go south after 30 days, so mix it depending on how much you use it. With this said, I don't think that fuel is his problem.

    Hi, i use echo 50:1 oil with 89 octane. the last time i ran the lawnboy i was using sears oil 40:1 with 87 octane and that was 1 or 2 years ago i'm going to drain the old gas and try the echo oil and the governer rod and see what happens..

    correct fuel/oil ratio is 32:1, after verifying point condition and checking exhaust ports and governor linkage you should be in business. use genuine lawn boy oil also- I work on lawnboy mowers and see some 30 year old machines every year from the same people who stick with the lawnboy oil. good luck!
