I have seen different procedures for the breakin of this engine.

I seen run it rich for a tank then two clicks back from max lean. Ive seen switch it back and forth between "four strokin" and "two strokin" for the first tank then little bit rich for the second.

I also heard the instruction supplied with this engine might not have the proper break-in instructions.

What is the true procedure?

Thanks

Thank You.

Should I perform break-in with a 10x5 prop for higher RPM, due to I indend to normally run with a 11x5?

Thanks again!

You can use the 11 x 5 for breakin. Won't hurt your engine.
