It sounds good, nice engine, and with 7 cylinders is a eye stopper !
the break in for this engine is 2000 rpm five minutes at a time until a full tank is used....in my case that’s 50 oz. That will take arbor two hours to accomplish. I have only gotten to run the engine for 15 minutes because the ignition failed during the third run. I have sent the engine to Horizon for repair and will update you when I get it back on the airframe
