Mix gasoline and oil at a ratio of 40:1. I added the instructions in the image below.

Mix gasoline and oil at a ratio of 40:1. A 40:1 ratio is obtained by mixing 3.2 ounces of oil

with 1 gallon of unleaded gasoline. This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality synthetic 2-cycle air-cooled engine oil. Often, if your exact model number cannot be found on, you could look at one or two model numbers above/below yours - if you can determine that the machines are similar, you have a good indication what replacement parts or operations can be used. That does not hold true 100% of the time, but it is something that I leverage from time to time.
