Starting a Flooded Engine

If the carburetor choke is closed (choke control fully extended) and after repeated attempts, the engine fails to start, the engine may be flooded with fuel. The fol- lowing steps are recommended to clear a flooded engine.

1.Move the “ON-OFF” ignition control switch to the “OFF” position.

WARNING!

The ignition switch must be in the “OFF” position to prevent the chance of igniting fuel and/or fuel vapors escaping from the engine during this procedure.

2.Push the choke control completely in to open the choke.

3.Remove the spark plug access cover and disconnect the plug wire. Remove the spark plug.

4.Inspect the spark plug for damage or excessive wear and replace if neces- sary. If the spark plug electrode is fuel soaked, or coated with carbon depos- its, clean and set the plug gap. Refer to the Specifications section for spark plug information.

WARNING!

Keep clear of the spark plug opening! Any excess fuel in the engine will be ejected through the spark plug opening during starter operation.

5.With the spark plug removed, the choke control pushed in and the igni- tion control in the “OFF” position, clear any excess fuel in the engine by repeat- edly pulling the starter until no evi- dence of fuel is seen escaping from the spark plug opening.
