N.B. In this paragraph the term „MIXTURE“ refers to the combination of the two elements: (air)
+ (oil\gasoline) that takes place inside the carburetor.
Changes in atmospheric conditions and height affect the functioning of the engine, in that they
vary the density of the air, as a result the air\oil\gasoline mixture ratio is modified.
As a general rule, we can say that a high altiudes, high humidity or high temperatures, less air
enters, and as a result the mixture is richer in „oil\gasoline“, so the correct ratio must be re-
established by tightening the two „H\L“ screws.
On the other hand, at low temperatures and low humidity, the denser air makes the mixture
lower in oil\petrol; as a result the two „H\L“ screws must be loosened.
CARBURATION
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
carburation 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 “45º”, larger movements in one turn can cause damage to the engine.
WARNING !!!
WARNING!
· Before starting the engine, ensure that there are no loosened screws or improperly
attached parts.
· Ensure that any people are at a safe distance and never in the range of the propeller.
· Do not start the engine if there are any stones or other objects nearby, as they could
be picked up and thrown large distances by the force of the propeller.
· Do not start the engine without a propeller.
· Do not start the engine in enclosed spaces, as the exhaust gases contain carbon
monoxide, which is toxic and can cause loss of consciousness and death.
Before sale, the engines undergo pre-running-in, to check the correct functioning, and a
test confirms all the advertised specifications.
Once you have acquired the W130, W200 you must pay particular attention during the first
hour of functioning, in order to maintain all the engine`s qualities over time.
WARNING!
DURING THE RUNNING-IN PHASE KEEP THE EXHAUST GAS TEMPERATURE AND
HEAD TEMPERATURE UNDER CONTINUOUS OBSERVATION.
