Another method that can be used for break in would be to set the engine between 2000-2500 rpm
and let it run for 4 hours. After that the engine would basically be broken in. Note: For break-in a
smaller propeller is recommended.
Important:
Remember that when the engine running ever
person must stay behind the line of the rotating propeller; never to the side or the front!
After Initial Break In
•
Use high grade fully synthetic 2-stroke oil
•
Use the oil manufacturer's recommended gas to oil mixture
•
We use 3W 2-stroke oil in our engines here in Germany, but there are other high grade
2-stroke oils that will perform well. The list below shows some 2-stroke oils that our customers
from abroad have used with success.
Note: The engine needs 12-20 hours running time for the break in process to be 100% complete.
Additional installation notes
•
There must be a minimum 4" separation between anything attached to the receiver and
all things related to the ignition (i.e., the ignition itself, and its wires, battery, and switch)
•
Use a plastic spiral sheath to protect the ignition cables
•
Never remove the sparkplug cap by using a mechanical aid like pliers. Only remove the
cap by hand using a twist/pull movement.
•
The spark plug cap must be firmly seated to the sparkplug. If the spark plug cap is not firmly
seated there is a very good possibility that you will experience radio interference.
