70hp not picking up properly

[Travller]

My 1998 will not accelerate properly and will only run full throttle and only then after laboring hard to get on plane. Have cleaned carbs. The nipple on the face plate of the electronic choke has broken but hose is connected. Does anyone know if my problem is caused by this or a cracked fuel line somewhere. Or should I install carb repair kits? Also should I replace the entire electronic choke part or just the broken face plate?
