Ok, so a quick update, but first, Happy Thanksgiving to everyone!!! The weather was absolutely perfect today. I flew the pee pee out of airplanes....got home after dark. I did fly my extra 330. Here is what I did for today's flights:

1) put a volt regulator on the ignition. I have been flying with A123s without a regulator because several forums suggest there would not be an issue. I figured for under 10.00, and because the DLE website says don't exceed 6 volts, it was a no brainier. Who knows if this fixed anything

2) richened up the low end. I had done this a while back when the weather was terrible and tested it on the ground. I was hopeful I had fixed the issue because it cranked right up.

And the results are...........drum roll.........bam.....idle is almost perfect. On the first flight, after landing, it seemed to slowly drop rpms till it died but the idle was perfect on landing. I leaned it a couple clicks and the second flight was almost perfect.

On on the second flight, after hand starting, the engine would cut out when advancing the throttle. I left the low end alone and waited for it to warm up and everything seemed fine. the landings and this setting were perfect though.

Is this scenario pretty common with gas engines, not being responsive until they warm up? I believe my XYZ 55 twin used to do it but haven't noticed lately. Who knows, anyway, I am happy, happy, happy.

thanks to everyone that assisted.
