I agree. . it's wayy to lean on the top end, probably close to 1/8 turn, but the bottom end seems to be about right.
I'd open the top 1/8 turn, fly it one flight, and see what the color is.

As for setting needles for a "blubbery" midrange, I think not. I set mine for a clean midrange and transition, with perhaps just a tad of richness on the bottom end for ease of starting and good cold (long "coasts" during landings need to be a tad richer in case of a go-around) throttle response. . .IF I can get them this way, then make sure teh top end is not too lean by looking at the sparkplugs.

I like to see a mid-tan colored center and side electrode, with a darker colored insulator and dk-brown/black body of the plug. White/powdery looking electrodes translate into too lean, a "glazed" looking insulator and wide "annealing ring" on the center electrode say too much heat. Black "specks" on a white electode say WAY too much heat and lean mixture, since pre-ignition or detonation are knocking carbon flakes off the piston, and they are coating the electrode. . BAD idea.

Go 1/8 richer on the high end needle, and forget about this "Max-RPM" frenzy. You do 90% of your flying in the mid-range. . . make the engine run best in that part of the rpm band, and the top end will take care of itself.
