What is the gas oil ratio for a weed eater 22 inch lawn mower?

40:1, or 1 gallon of GAS per 3.2oz of 2-stroke oil

Improvement;

Your 22 inch Weed Eater push mower has a four stroke engine. You do not mix oil and gas, there is a reservoir for the oil and a seperate gasoline tank. The oil goes in the bottom of the engine where it mates with the mower housing. There will be either a small dipstick or a large screw that can be turned by hand. The engine requires either 10w30 or straight 30 weight motor oil. the engines typically hold 28 ounces of oil.
