Hi Keith. Just some speculations. The egt would rise because of lean mixture, right? If the ignition was over-advanced, it would result in less power because of excessive pressure rise on the piston before tdc, and maybe detonation on the power stroke before the exhaust valve opened. I gather detonation is the result of a number of factors, one of which is ignition timing, others are fuel characteristics, compression ratio, combustion chamber design, turbulence, rpm, etc. Bill |
