RO-JETT 51 Break-in Run

New RO-JETT .51 Bar stock, side exhaust version, recently received from Dub Jett. I am following the RO-JETT break-in instructions. Prop is a 10x6 Graupner; fuel is the RO-JETT recommendation (10-22 with 5% of the oil being castor): Plug is a Merlin 2004. After starting and short warm-up, I set the engine to run at the break, cycling in and out. Run time on 1.5 oz. of fuel was 2:27. Recommended break-in is 1.5 to 2 hours on the bench.
