Happy news: I have put 20 hours on Fergie since her return, and she is "purring like a kitten" (maybe one of @Shawn T. W.'s). Great to have all three cylinders working.
That's GREAT news!

Nothing like a Happy Content Kitty curled up in your lap with its little motor idling along!

I too have never understood the "high idle" terminology ... In semi-trucks our trucks "idle" 600-700 RPM ... We can bump up the "idle" via cruise control while parked to 850-950 RPM for "high idle" ... A little
better oil pressure, and heat build up, redline is about 2500, normal operation is 1100-1500 RPM ... Also bypasses the stupid 5 minute idle restriction that California has forced on the rest of the country ...
I rarely run mine into the yellow zone, but really it's the red zone they frown on, I'm not sure it will even go there, if the governor hasn't been fiddled with ... My understanding is to vary the RPM while in the "break-in" 1st 50 hours ... I don't remember the actual phraseology, but it's in the manual ... I'm not at home now to look.
While I waited until 49 hours for my 1st oil change, I was planning on doing it at 25 hours, just got too busy USING the handy little tractor! I figured any initial "wear" would be done by then, and I wanted to get it out of there ... I tend to change fluids "early"!
