I have been reading about what people are thinking the cylinder head temperature should be after running the engine for several and have read some people say 300 and some degrees. That seems extremely HOT to me. Could you guys give me a response on this topic and tell me what you think a normal runnning temperature on the cylinder should be. Thanks

Check last months issue of Model Airplane News (April 2002) for an article by Dave Gierke on engine head temperature.
