Anyone have any more suggestions on break-in tasks? I re-read some archived posts on the subject. It sounds like I should keep it under 3000RPM for the first hour or so and then move it up.  Beyond that, and with no more leaks to fix, I’m at a loss to know what, if anything, I need to do. I really didn’t expect it to be this easy.

Count your blessings; and keep on runnin’.  I had probably about 2 hours on my engine when we started dong the WOT power runs on the dyno; and I have no reason to believe that did any damage.  I’d only expect that the power would be a bit higher after more hours.

 

Before first flight I want to have at least 10 hours of ground running done with at least 1 hour at or above 5000 RPM – and that 1 hour can’t be the last hour.

Sounds like a good plan; spend your time getting mixture and other measurements dialed in.  I’ve got about 7 hours on mine with dyno runs and runs on the plane, but only a few minutes at WOT at about 52-5300 rpm. I expect to get the hour or so of full power ground runs after I get to the airport.

 

Should I be checking compression every so often? Timing? Tear the engine down and Mic all the parts J ?

 

If it’s running smooth and putting out good power I see no need to check compression – unless you really want to.  Can’t hurt to verify timing before you go fly.  Look for anything that might be vibrating – lines, wires, etc. and get everything tied down; not just in the engine compartment, but anywhere on the plane.  Think about teardown to check wear after about 2000 hours; or some clear indication of something not right.

 

Sounds like you’re doing great.

 

Best,
