No it's not. He doesn't have enough timing. That's probably THE biggest mistake made when breaking in an engine. With timing too far retarded, the mixture is igniting too late and still burning coming out of the exhaust. That will heat the engine up real quick. It's also very apparent on a new engine, because they are tight and have more resistance to running, which builds up even more heat. The best thing to do is, as SOON as it fires off, run it up to about 3000 RPM and pull in AT LEAST 35-36 degrees and more won't hurt a thing, since it's under ZERO load.
