PRE-START
4.2.1
Fill fuel tank. For best results use only clean fresh regular grade
unleaded
gasoline with an octane rating of 87 or higher. Regular grade leaded gasoline
may also be used; however, combustion chamber and cylinder head will require
more frequent service. See Engine Owner's Manual. Do not add oil to gasoline.
Do Not
overfill fuel tank. Never fill the fuel tank so that the fuel level rises above
a level that is 1/2” below the bottom of the filler neck to allow for fuel expansion
and prevent fuel spillage.
4.2.2
Refer to Maintenance and Adjustment Section 5 and perform all of the necessary
inspection and maintenance steps.
4.2.3
Make sure you understand the controls, their locations, their functions, and their
safety requirements.

throttle lever midway between “Slow” and “Fast” positions and leave the choke in
the “Off” position.
Turn ignition switch to “Start” position. Release the switch as soon as the engine
starts.
On a cold engine, gradually return choke to the “Off” position after engine starts
