I'm not sure on my exact needle settings but I just switched to the new 30% on my WS9 and had to lean out the low end and the top end quite a bit, I think it was close to 12 hours on both, sorry I can't be more precise.
Given your reduction in run time I'd say it's too rich now as well.
Perhaps leaning out the low end will help your idle too.
I run RB #7 plugs.
