ran fine one day then the next it bogged while cruising at 3/4 throttle, when i came out of the throttle it ran slowly just fine then when i pushed the throttle it bogged again. i have isolated it to the bottom carb or cylinder. i ran motor at high idle and sprayed carb cleaner in each one top two carbs both made the motor rev up, motor bogged when i sprayed in bottom carb. i also changed plugs to make sure not fouled.i checked for fire on each cylinder and all were good. i think that that carb is giving too much fuel, is there any kind of adjustment i can make?
