Help!
How to break this engine??

Hi guys, I'm new here and sort of new to flying gas airplanes. I recently bought this cox engine (R/C Kuro Customized Cox .049 Model Airplane Engine/ Exhaust throttle) and arrived today to me. I want to use this in a one of my large electric plane but I don't know how to break it before mounting the engine. This is a brand new engine and I don't know how to use it for the first time. Any detailed help would be nice.

Here it is:


regards,
Erika.

Here is instructions on operation and breaking in the engine: http://coxengines.ca/pages.php?pageid=6

Here is what they say for breaking in a engine:

A brand new engine should be broken in. Simply run the engine for one full fuel tank in a very rich mixture setting. Let the engine cool off and repeat with a slightly leaner mixture (higher RPM). Repeat once more at almost full RPM and you are set to go.

How large a plane?

A Cox .049 is equal to about a 70 watt electric motor.
