5. BREAKING IN PROCEDURE
DO NOT RUN THE ENGINE WITHOUT PROPELLER AND EXHAUST SYSTEM
Each Simonini Victor 2 plus / Victor 2 super engine is assembled and run in at the factory.
Each engine is subjected to a dynamic test. The engine is securely mounted on a test bench and a
suitable propeller installed on it.
The engine is started and kept running for up to 4 hours at variable speeds.
Temperatures and power outputs are regularly checked while the engine is being run.
The customer/user is not required to do any running or breaking in procedures on the engine.
The carburetors are set at the factory for the ideal settings.
When the engine is mounted on your aircraft, ensure that both carburetor settings are equal when
installing the throttle and choke operating cables.
Adjust the carburetor slides until you get an 8 mm gap under the slides when visible from the air
filter side.
Turn the carburetor airscrews fully close and then unscrew them by 1 to 1. 5turns.
With the throttle completely closed and the choke in, you can start the engine: do not run the
electric starter for more than 5seconds. Once the engine runs, please wait for 4/5seconds then you
have to leave the choke progressively until the engine runs correctly and regularly.
Once the engine has been warmed gradually (1-2minutes) accelerate and stabilizing the gas at
about 3800/4000rpm.
Now you have to reduce the engine rev at the minimum (adjusted at 2000/2100rpm per minute). If
it does not work this way, please adjust the two idle screws and set them better.
