Hi Chuck: 

 

We've pretty much covered what could have been wrong with your engine... one thing I'd be curious to know, that would give some insight... do you have mulitprobe CHT/EGT and were you able to sneak a glance during any of this?

Hi, 

   For the first 100 hours or so of running the engine, I borrowed a portable engine probe to monitor the cylinders and found them all to be close. After doing that, I installed only single probes on the hottest cylinder.  

   Since the incident I have put another fifteen hours on the engine. At cruise the engine appears to be running smooth. But I find I have to make slight adjustments to the mixture and prop control. The idle appears to be rougher than usual, especially when I get it down around 1,100 RPM.  

  I read an article about induction leaks. The article said that at 650/750 RPM an engine should only be pulling 10 inches of manifold pressure. Mine pulls 15 inches at 850 RPM and the engine wants to quit. When I manage to get it to 650 RPM the manifold pressure shoots up to 18/20 inches and just about quits. I am sure the low rpm mixture is set right.  

       My return trip back from Washington was a white knuckle trip. To avoid building thunderstorms, I had to fly the whole return trip on top an over cast over the Blue Ridge Mountains all the way back to Atlanta. Just as I reached the Harris VOR  Fight control advised that I land at the nearest airport because of thunderstorms and blinding heavy rain. "Blinding rain" rain was a first for me. Several aircraft were just circling out side the system and watching it on their storm scopes. I had to land because I only had a few gallons left in my main tank and my header had only 5 1/2 gallons.
