To break in the engine

2 gallons of fuel 25:1 mineral oil propeller 16X8 or 18X6 depending on the airplane need. Little bit rich mixture, The break in flying the airplane, avoid steep climbs or manuevers that need alot of power.

Engine is ready to run, Oil to gas 40:1 using syntetic oil, change the spark plug to a new one, you can adjust the mixture to normal and use the propeller that your aiplane nedds
This particular engine seems to have max torque at 7500 rpm I have it in a Yak with a 16X10 apc runs great.

best regards
