IMPORTANT TANK LEVEL SETTING: THE SHEET HOLD FLOAT MUST BE PARALLEL TO
THE BODY CARBURETTOR FLANGE AS SHOWN.
If we remark a different value, please operate on the two metallic plates which
support the floats, to obtain the prescribed level.

both
floats, to obtain the same.
Whenever an optimum carburettor setting is required in each condition, it will
have to be performed by acting on the adjusting elements to better fit the most
proper mixture title according to the track and environmental characteristics.
