I just re-read my post, I forgot to mention that with the glow plug igniter on it would idle just fine and at WOT it seemed to have more power as well.

I will try your suggestion to make the LSN richer and the HSN leaner. I did think it was odd when I had to turn the HSN about 1/2 turn richer to get it to run right a WOT. I had this engine running just a few weeks ago with the old piston and I didn't change the carb settings.
