Been tuning alky so long, stock carbs are kicking my ass. Got a good deal so picked it up. Anyway Stock stroke, stock bore, cool head, pods, and t5s. 280 mains give a nice plug chop. Needle in middle clip. And thens my problem. Idles good. But right off idle it stumbles. Tried 30 pilots and played with air screws. Dropped back to 25s and it's still not crisp.... What jetting would you suggest? 145psi. Passed leak down, reeds nice, carbs spotless..
