There's a bit of a difference between 'not liking' something and that something being 'dangerous'.

Don't be the new guy that wants to change how we do things.
Nobody likes that guy.

And just to be clear I'm not trying to be an @ss.
Just commenting on your situation based on my experiences.
Learn from the event.
I'd still try and get my job back if I were you.

I didn't think you were being an @ss. I actually appreciate your input.
That's just it, it's not that I didn't like how things were done--i felt like the way things were handled was causing undue risk. And I didn't make a big stink about it either, I simply decided it wasn't a fit for me and left. Now I'm just trying to share my experience so people can make a more k formed decision.

That's obviously not what happened. Pulling 0g for a few seconds won't do anything. Where exactly does the oil go "where it shouldn't be" when you pull 0G?

He may have been running rich, plugs loading up, finally had enough, coughed...and miraculously cleared with a slight mixture adjustment big clue).

He may have had a stuck float or flooded with the zero-g. It can happen

Bottom line is the responsibility of the pilot in command to assure the safe conduct of the flight.

Beggars and choosers. The origional poster cant decide which he is.

All of those are completely plausible scenarios. Saying "oil" got into places it shouldn't get is not.

Is the OP a CFI, out of curiosity...?

It's also plausible. Do you understand why?

In an O-320? No I don't understand why. Even if you drown the bottoms of the cylinder barrels with oil (which won't happen in a short 0G event anyway), the piston moving down will easily push the oil back to the sump, the breather takes care of that (less resistance going through the breather/back to the sump than seep past rings). This is a Part 23 requirement as well (23.943).
Acrobatic planes with no inverted oil systems run just fine, even if inverted briefly.

Please tell me how this is plausible.

Aerobatic airplanes without inverted systems are best flown with positive G.

And obviously neither do you.

Those engines will not fail nor will oil go to wrong places causing rough running during short term 0/negative G flying.

I'm very certain it was a case of the carb float sticking in the open position. While not catastrophic, this shouldn't happen. The fact that this happened wasn't a huge deal to me, the point you're missing is how it was dealt with. At one point I was told that my airspeed and rpm indications were inaccurate and the whole event was basically in my imagination. Also, don't miss out on the reason I left (point #2 of the original post), this is just another observation that I wasn't particularly impressed with.
John, perhaps "partial engine failure" is a bit over dramatic. If it seems that way, that's not how it was intended--the engine is supposed to produce so much horsepower and it didn't, sounds like a failure to me. Would you complain if I call it "partial power loss"?
