Engine "drowned"

i

Note

When the choke is closed and the starter rope is 
pulled several times, the engine draws in too much 
fuel and will probably not start.

Remedy

l

Close the fuel cock.

l

Open the choke.

l

Set the throttle lever to full speed position.

l

Operate the recoil starter until the engine 
starts.

i

Note

If the engine does not start after 10 to 20 attempts

l

Open the choke.

l

Set the throttle lever to full speed position.

l

pull off the spark plug socket.

l

unscrew the spark plug.

l

operate the starter several times.

l

Dry the spark plug with a clean cloth or blow it 
dry with compressed air. If necessary clean 
with a wire brush.

l

Screw the spark plug back in and plug the 
spark plug socket back on.

l

Danger

Danger of accident!

Steer the vibratory plate only be the steering 
handle.

!

Caution

Operate the vibratory plate only with full en-
gine speed, as otherwise the centrifugal clutch 
will be destroyed.

For short breaks you should always return the 
throttle lever to idle speed position, this avoids 
premature wear of the centrifugal clutch.

Fig. 26 

l

Shift the throttle lever (Fig. 26) in direction of 
arrow to full load position.

The vibratory plate works with highest frequency.
