Seems like we have had about the same experiences. I'm glad this forum started, I thought it was just me.
Some very experienced members at my club (200 + strong) tried to help with no avail.
I'm not sure ignition timing is the problem ... some 2-cycle enging dont have timing advance features, plus, after sending my engine back to DA, if it was off, I think they would have made adjustments.

Last year in an attempt to get some flying in ... I did lean the engine out until it would "just" quit when the throttle was advanced rapidly ... But it would idle OK.
Then I used throttle delay to keep it from quitting.
I then had to richen the high speed needle a bit.
It did not quit in the air at all .... only on the last flight ... turned out to be another ignition module.

I think this is why DA told me my needles were "way out" when I sent it back.
But their settings didn't work when I tried it for the first time last week. It was worse than any settings we tried.

I will go back to my previous plan.
