This engine is a  2-stroke gasoline engine requiring a specific
fuel to oil mixture of 50:1(2%). It is recommended to use an
unleaded gasoline rated at 92 octane (
premium) with an oil for

will prolong the life of the 
main filter element.

water. Let dry thoroughly. When dry, completely coat the filter
with only an approved
