2001 Johnson 70

I’m pretty sure I know the issue is a gummed carb. Runs great on muffs. But when out in the water it dies. Which style of carbs do inhave. Do I have the long needles or the orifice carb? Inhave the boat sold. Just gotta get it to go across the lake. Any advice on how to clean it up? The 3 carbs linkage kinda throws me off for pulling them.

It only sounds great on muffs.----They all " bark and roar " even running on 2 of 3 cylinders.----Or a V-6 running on 4 or 5 of 6 sounds wonderful.
