Hello all,



We returned home yesterday from East Coast visits following LOBO mtg in Gr= eenville, SC.



On the way to Greenville after an intermediate stop in NE, we experien= ced an engine problem that I brought to the attention of anyone at LOBO who would listen and give advice including Ne= il George from TCM with Allen Barrett h= ooked into the discussion by text and cell phone.  

 

 

The short story is that when I reached my planned VFR alt= itude of 15,500 and levelled off I pulled back power but forgot to lean or r= eset prop for about ten minutes.  Then when I remembered and tried to l= ean the engine, TITs skyrocketed followed by hot EGT readings.  See the= attached link to the Savvyanalysis gra= phing of the engine behavior and see if you can come up with what went wrong= .   When you review the graph, you=E2= =80=99ll likely notice that I tried twice more after the initial leaning to s= ee if I could get lean of peak and the engine emphatically let me know it di= d  NOT like what I was doing.



I= can tell you the problem has been reso= lved and we flew the airplane around the country for another week with no repeats.  Now I'm interested to know= what LMLers might think caused this because I= was totally surprised when I learned what the real problem was.=

Some of y= ou who were supportive at LOBO already know the answer so let=E2=80=99s see w= hat others come up with.   I have many people to thank for amazing= help in finding and correcting the problem so I want to go on record as one= of the most appreciative people there could be for LOBO, our many vendors a= nd for pilots around the airport in Greenville who gave advice, time, materi= als, loaned tools and so on.
