Starting the Engine
The new Evolution Engine carburetor comes adjusted to a
basic setting. This setting should be maintained during the
initial break in runs.
Before you first start the engine, make sure that the spark
plug is screwed in and tightened and that the plug socket
is fitted in place and fastened down properly. Fix the ignition
sensor in the proper position above the magnet with the
screws enclosed. Follow the directions in the Ignition System
addendum to program the ignition module in your model.
Important: Never turn the engine over with the ignition turned
on unless the spark plug is inserted in the plug socket. This
could lead to ignition damage.

2-stroke gasoline engines. For the run-in period of the new engine, mix the fuel in a ratio of 30 parts gasoline to 1 part lubricant. After

Starting With Easy Start Feature
1) Make sure the ignition switch is on and the throttle is set at a slightly high idle setting. Be sure to have a helper hold the model
securely. The Easy Start feature will have the choke closed at this time. Give the propeller a few quick flips. If the engine starts, the
Easy Start system will automatically open the choke, and modulate its position as necessary to keep the engine running until warm.
2) If the engine does not start immediately, please note the following:
a) The Easy Start System will keep the choke closed for the first 4 flips of the propeller, then;
b) The choke will go to a half-open position for the next 4 flips of the propeller, then;
c) The choke will be fully opened for the next 4 flips of the propeller, then;
d) The Easy Start system will start the entire sequence over again by closing completely the choke.
3) The above steps assure a situation that will not flood the engine, and allow for easy starting procedures, whether it is your first, or
your tenth, flight of the day.
