In general, we can say that at high altitude, high humidity or high temperatures, less
air enters and therefore the mixture is richer in oil/gasoline: you will have to re-
establish the proper relationship by screwing the two screws "H/L”.
In contrast, with low temperatures and low humidity, the air will become denser
than the lean-burn oil / gasoline, and consequently you will have to unscrew the two
screws "H / L".
WARNING: A mixture that is too low in oil/gasoline causes considerable damage to
the engine, which can cause it to break down and/or stop suddenly. It is
recommended to carry out the carburetion operations with the ENGINE SWITCHED
OFF.
When the "H / L" screws are tightened/loosened, carry out variations of 1/8 of a
turn each time or "45°", larger movements in a turn can cause engine damage.
RUNNING-IN
WARNING
• Before starting the engine, make sure that there are no loosened screws or
improperly attached parts;
• Ensure that any persons are at a distance of absolute safety and never in range of
the propeller;
• Do not start the engine where there are rocks or other objects that the force
generated by the propeller can lift and throw even at a considerable distance;
• Do not start the engine without propeller;
• Do not start the engine indoors: the exhaust gases contain poisonous carbon
monoxide which is toxic and can cause loss of consciousness and death.
The engine, before being sold, was subjected to a pre-running-in to verify the proper
operation and a test that confirms all the features advertised.
Once you require a MINI 2 EVO, you should pay particular attention to the first hour
of operation, in order to ensure all the engine’s qualities over time.
