Out trolling the other day on a swing turn running over half throttle the motor started to cut out and almost die..It would idle,low RPM & start fine anything over half throttle it wants to die.pull the choke out half way and it runs ok..but not the same! I changed the Plugs an fuel filter, Didnt change a thing! I bet it doesnt have 40 hrs on it!..It was sudden I checked for water in filter couldnt find any or any dirt, Plugs looked great! :sick: Any ideas??

If it runs better with the choke out you should remove and thoroughly clean the carb

How is the fuel vent? Open? Clear?

Thanks Boat Doc & Et, I already checked the vent,,pin holes in fuel lines etc...so I pulled the carb,,,No Water,, But very small particals of dirt in the float bowl..So Got out the carb cleaner and it runs fine now.
Thanks Dave
