RE: EGT problem
360 engine, traditional mags, Dynon D100/120 instrumentation, RV7A
700 plus hours, fuel injected.
Last flight during some aerobatic stuff the pilot noted the #2 cylinder EGT redlined at 2000 Immediately retarded throttle and headed home. Throttled back the EGT fell back into the Green.
Thinking it might be an anomaly, and after the plane sat for a cool down, saddled up for an other flight. Everything normal until full throttle and lift off the same thing happened along with noting the EGT immediately up to 2000 and CHT higher than normal (didn't note the temp???). So immediate throttle retard and back to the hanger.
Maybe an injector problem....Cleaned the injector and
So a static run up .... brakes on throttle in to about ??? 2000 plus rpm and at about 15 or so seconds the EGT again made the immediate climb to 2000 plus and the CHT climbing. Again retard the throttle and start the trouble shooting process. Local engine gurus will be consulted today, will try to round up a scope to eyeball the internals of the #2 cylinder in question.
My thought is maybe a mag problem, probe problem, instrument problem??????
Any ideas from you engine gurus would be greatly appreciated.
