Engine Break-In Process
A good break-in process is essential to the longevity and performance of your Evolution radial
engine. You can complete the break-in process by either mounting the engine on a test stand
or on an airframe. If you choose to mount the engine on an airframe, remove the cowl during
break-in to ensure adequate cooling.
Specific fuel is required for the break-in process. Please refer to the chart above for the proper
fuel. Break-in fuel contains additional oil compared to fuel you will use for everyday flying. The
additional oil is critical for cooling and removing break-in debris from the engine.
During break-in, run the engine for 3–4 minutes at a time, allowing the engine to cool between
runs. Vary the throttle between idle and ¾ throttle for the first 30 minutes of engine run time.
The engine break-in process will be complete after the first 3 hours of engine run time and
you can begin tuning the engine for normal flying.
Checking for a Flooded Cylinder
Because of the nature of radial engines it is not uncommon for the lower cylinders to accumulate
excess fuel or oil either in storage or during the priming process. Before beginning the starting
process be sure to:
1. Rotate the propeller by hand. During the rotation, if you encounter a point where there is seri-
ous resistance to the rotation, STOP. This is an indication of a flooded cylinder and what you
are feeling is hydraulic lock. Any further attempts to force the rotation of the engine can result
in damage to the cylinder or conrod.
2. If you encountered hydraulic lock, remove the glow plug from the lower two cylinders and the
engine should rotate freely. Continue to rotate until all the excess fluid has been removed
from the cylinder.
3. Reinstall the glow plug and continue with the starting process.

Starting the Engine

Use a high quality gear oil to lubricate the outer parts of the valve train at the beginning
of each flying day.
1. Fill the fuel tank with fuel.
2. Power off or disconnect the glow driver.
3. Make sure the fuel lines are properly connected to the carburetor.
4. Open the throttle to full open. The carburetor barrel should be fully opened.
5. Place the choke lever over the carburetor opening.
6. Rotate the propeller 3 or 4 times until you see fuel moving through the fuel lines.
7. Remove the choke lever from the carburetor opening and move the throttle stick to ¼ throttle.
8. Power on or connect the glow driver battery. Make sure the glow driver battery is
fully charged.
9. Start the engine with an electric starter.
