Tuned by me with a tach 12500 rpm holds in wood 8500-9000 rpm.The H jet is 3 turns out.
I use sthil hp ultra 40:1.
Is too rich?
Tuned by the dealer without a tach H jet 1 1/2 turns out and is hitting the rev limiter.
I think is too lean?
Thanks!
I'd go along with those thoughts.

Keep in mind that outside air temperature plays a big part in the apparent mixture setting. Colder - they go leaner   
Warmer - they go richer
