Caution!
It is better to adjust your engine a little too rich than too lean. If the setting is too rich, your
engine may not run with the maximum possible top performance.
Too lean a setting can lead to insufficient lubrication with enormous wear.
In an extreme case it can cause complete damage of the engine, and the guarantee will expire!
• If you have found the optimum carburettor setting for your engine at operating state temperature, the
engine may not run properly when it is cold. In this case, do not immediately turn the carburettor needles,
but leave the engine enough time to reach operating temperature.
