Re: 1991 force 120 decelerates after hitting top speed
So with all the troubleshooting you did and finally resolving your problem, what do you think was you final diagnosis? Restricted fuel lines with faulty needle setting on the bottom carb? The restricted line problem should have easily been identified with the installed clear fuel filter between fuel pump and carb since it will ran empty or at least low fuel level when the engine starts to bog down at WOT. Unless, the bottom carb causes the bogging down before it becomes empty or low in fuel level. The combination of having two such problems made the troubleshooting difficult but you did it and learned a long the way. Congrats.
