Hey 610-ers, I've had great results with the much heralded 610 set up that is all over these pages since I got my '06 back in the fall. 180main, 45pilot, irridium plug....etc. That is until hot weather got here, now I've got a stutter at 6500rpms. I went back to the stock 172main and it brought the miss down to 5800rpms. Now I'm concidering going back to the 180 and making the change at the needle position to lean 'er out. Anyone else leaning out with the needle for warmer weather?
