1. The break-in process allows the engine parts to perfectly fit to each other and properly protect the parts against unnecessary wear. The engine should be broken-in using a fuel with no more than 15% nitromethane content. Castor oil is important to the break-in process. Fuels with all synthetic oil content should not be used. Do not mount the engine in a vice or similar device. The most effective place to break-in the engine is in the plane in which the engine will be used. This way, the muffler, tank, and throttle linkage that will be used during flight will be tested in combination with the engine.
