e) Description of the Carburettor
The carburettor of the installed "FORCE" combustion engine is distin-
guished by a plastic and metal material combination. The lower heat
absorption as compared to a full metal carburettor reduces premature
vaporisation of the fuel mixture in the carburettor.
This way, it is easier to adjust the fuel supply even if the engine is hot.
Once a carburettor setting has been selected, it remains reproducible
and constant during operation.

Caution, important!
The carburettor is already pre-set for operation ex works. Therefore, do not twist the adjusting screws of the
carburettor at initial commissioning of the vehicle.

of the carburettor.
Fine settings of idle and full throttle are only possible with the engine well run in. Do not perform any adjust-
ments at the carburettor until the engine has at least run for 2 - 3 hours.
Only adjust the screws in the carburettor in very small steps (max. 1/16 turn) and record the changes or
rotating direction.

If you have never set a model car carburettor before, ask an experienced model sportsman before you
perform any settings.
