Change/adjustment of the spark plug
Attention! Worn-out spark plugs or too large distance between breaker
contacts decrease the engine performance.
▪
Turn the unit off.
▪
Disconnect the sparkplug cable from the spark plug.
▪
Unscrew counterclockwise the spark plug with a spark plug key. Do not use any other tool
in order to prevent any damage.
▪
Use a control template (available at specialized shops) and check the distance between
the breaker contacts. The distance must be 0.635 mm.
▪
If necessary, correct the distance by carefully bending the ignition arch of the spark plug.
▪
Clean the spark plug with a wire brush.
▪
Insert a cleaned and adjusted spark plug or replace the damaged one by a new one.
▪
Reconnect the spark plug cable.

Carburetor adjustment
The carburetor was adjusted to optimum performance already during production. If the
carburetor requires readjustment, have it done at a specialized expert repair shop.
