When testing, I've noticed that the spark plug has to be cleaned throughly between runs. Reason might be that the gasoline has still too much oil in it. Even when running the engine on ethanol without oil, the spark plug had to be cleaned before next run, or engine fails to start. After all, there is still some run-in to do, to find out how well the new piston/cylinder -combo keeps its tightness. |

Sounds like a fine ticking watch running. Bernd |

Today was the longest running session so far (~30 minutes), at a wonderfully low speed (1200-1400 rpm) :nrocks:. I'm not sure if it's possible for an engine that small to run any slower, but I'll try it anyway :wave:. |

Well done, looks like it's running superbly. Might cooling be an issue running it any longer than that? Nick |
