reaches higher rpm.
Replacing the propeller the carburetion changes. If the propeller is overloaded and
the engine speed does not reach the previously established, we must put a bigger
jet. However, we recommend the use of propellers already experienced by us as a 2
blades wooden propeller by GT Propeller, cm 164.
LUBRICATION
To prepare the mixture of oil and gasoline, we recommend using a semi-synthetic
lubricant, which exceed the API TC, JASO FC, (for example, BARDHAL Plus VBA or API
Mixoilsint).
The oil percentage to be used in our engines with liquid cooling, varies from the oil
type used:
3% if you use unleaded petrol (unleaded)
2% if you use leaded gasoline (premium gasoline).
To prepare it appropriately, we recommend to use clean tanks, put first the oil and
then enter the correct quantity of fuel in the tank.
Later, with the tank closed and holding it firmly in your hands, flip it over repeatedly
allowing good mixing of the oil and fuel.
