Tune it. You're losing 500__800RPM somewhere.

I don't have a G62 in the fleet that won't turn 7000+ with every 22-10 prop except a Bambula (boat oar). I got 5 of these engines.

Most 22-10 props should be turning 7000__7300RPM.

Lean the high speed needle out to peak and then back it up about 200__300RPM. Check the low end for transition and sputtering. If it's sputtering in the midrange__it's rich on the low speed needle. Lean the low end until it stops sputtering. If you lean the low end too far, it will become troublesome to start. In that case, fatten the low speed needle 1/8th turn and go for it.
