Hi jharkin Thanks for the note!

I have not flown it like the proud grandpa I am for about the last 5 gallons. I 3-D the hell out of it and it likes it now!

I guess my point was most all the things I read about were not the problem regarding inverted dead stick on "my" engine.. The only things accurate in "my" case was break it in and tune!

My engine is newer and I am aware of issues years ago so who knows there on yours

With regard to 6 months experience I do have a 15 year old level 1 certification (carb,gearcase) from Johnson Evinrude for 2 cycle outboard engine repair.

Does that count....................... at all?

Gonna guess I've seen a whole bunch more 2 cycles that you, but yeah sorta different critters for sure. But..I get it

I am 57 years old and grew up on 2 cycle everything, and vapor lock is very recognizable. I'm gonna guess it can also cause things to be wonky if she runs and flies but still can't breath right

That said behavior between the two applications (air vs water) will be different and that is where I am a newbie

Yeah I have put this plane through it trying to get the engine to die inverted now, and it just won't....... now.

I did activate an idle down to land on so I can keep a higher idle for normal flight.

My experience is just that, and as it is, it's very valid. I worked through and solved the problems on "my" rig. Do engines have gremlins.....hell yeah they can but "mine" did not. It needed tweaking and break-in.

Not sure if your have fuel line rigged in your cowl with that 50. If so try getting "all" of it out and see if that helps. Who knows if these engines can "run" fine right on the edge of vapor lock but as such die when inverted at that stage?????????????? Worth trying???

You "may" need to tweak needles after you move fuel lines. I did just a hair

Quote("Fly that plane harder... you WILL deadstick sooner or later in an inverted move") Have flown for many consecutive minutes on high idle.............just keeps going??????????

Please advise!
