And, now that we've come full circle about the algae --------bag is terrific filter not allowing algae to get out of it ----- what about the idle shutdown occurrence/syndrome? Unexplained idle shutdown has only happened three or four times in my Jet Cat experience, but those three or four times really puzzles me. Damn, the Jet Cats operation is otherwise so perfect, these unexplained shutdowns really bug me. Jet Cats are so close to perfect when something is slightly screwy it really sticks out like a sore thumb----.

Nat says I should idle up to about 35,000 for cooler operating temps, possible elimination of the shutdown syndrome, and better throttle response times. Well, I tried it and noticed I needed slight braking during taxing, and it seemed like I was being pushed a little during landing. Nat claims that the idle up RPM's don't increase idle thrust noticeably, but I thought I noticed a slight more push on idle. Bottom line I re-set my idle to factory default of 33,000, I'm stubborn!

Fact is I had Bob change limits so I could idle down to 31,000 RPM's. I've only tried that once or twice, with no idle shutdowns but have basically stuck with the factory default 33,000 ---------- Also, a note here out of the four idle shutdowns I have experienced one of them was my P-80 in my MIG, and the three others were in my P-120 powered Bob Cat!

Not complaining a bit Bob just puzzled, why does it happen? Seems like to me a slight software change with a built in time delay of sorts could eliminate any unwanted shutdowns -------
