Scott,
sry for the delay, I was on a short visit at my parents..
I got the P3D version on P3Dv3.2.
It's weird, reminds me on the clickspot thing. sometimes it happens, sometimes not. I found it hard to reproduce it on purpose after I let the aircraft parked after a reload for about 2 hours. But before I wrote 3 hours ago I was on level autopiloted flight with 25-26MP, 1800RPM on 8000ft and leaned mixture with the lever half back. Then I had the idea to do some clean stalls, go into a spin and during that spin the engine cut. I did an emergency landing as I couldn't make it start in flight. Then I put the airplane back to friday harbour using the airport selection and couldn't start it eather. it just did as described above, it burned the primer fuel. With an aircraft reload it worked as it should. Gs were not that much negative, just the stick fully forward at maybe 130-140mph. -1/-2g approx.
Now I tried to kill the engine again in flight and it caughed, but caught itself as soon as the Gs were stable positive. Both leaned and rich. same power setting. then I cut off the mixture and brought it back to rich and it did NOT restart. Now I'm paused in flight with turning prop, mags on, mixture rich, carb mixt (!) and carb heat half way back. I am not sure if the carb heat was on 3h before, but I know that the carburator was not iced.
I will do another emerg landing and try to start the engine on the ground.
edit:
does not start on the ground.
looks like once you cut the fuel in flight you cant bring it back (maybe depending on MP and RPM? I don't know your coding
)
