Hey Randy ... et al ....

The low end mixture screw .... what is about the right setting, or number of turns out to get started. For giggles, I turned mine all the way in to see where it was set and it was around 3 and a half. I went ahead and backed it off to where it was and added another half turn.

My main is set around 1.25 out, and things seem to run pretty well at power. I have tried backing it out a half a turn to get it started and warm up, and then adjust it back when it settles down. I could try richening it up further.

I think you are onto something with the low end adjustment though. I have never touched that so far ...
