Stalling Problem

[GeorgiaboyIII]

My 1992 Yamaha 115 HP V-4 stalls or bogs down on acceleration. When I hit the electric choke it picks up and does the same each time I hit the choke. Have replaced filters, plugs and primer bubble with no improvement. Any ideas as to the cause?

Carbs. If it's fine when you push the choke, it's probably the carbs.
