Ive been having problems with the boat motor weak and surges at wot.The carbs are clean and ect.Im thinking it needs to be adjusted but where is the adjuster?When i hit the electric choke it gives it a guick boost then back to serging.

Re: carb help

Your motor doesn't have a high speed adjustment. The high speed jet controls the fuel flow. It's located in the bottom of the float bowl and is sometimes overlooked when cleaning the carb. However, your issue may not be the carb, it kinda sounds like the fuel pump may be weakening or leaking.
