40hp 1995 force dieing at wot

[Basstracker95]

Hey I have a 1995 40hp 2 stroke force that dies if I go wide open throttle. If i gradually give it gas it will work its way to full throttle and then die. I just replaced the primer bulb. Any other ideas?

I have an in-line clear fuel filter to see I am not starving for fuel on my 35 HP Chrysler (if running issues occur).

The last thing you said was you changed the bulb: even new they can be bad!!
​Any inline connectors, they have rubber seals in them and the seals can go bad and allow air to be sucked in and interrupt the flow.
​The tank vent could be clogged. Bugs get in the vent(built-in tank)line and cut off the air.

Don't forget about the fuel pump diaphragm too. It should be replaced as well as the water pump impeller on a regular basis as a normal maintenance routine.

I just replaced the fuel filter and fuel pump im going to try it tomorrow.

Try pumping the ball then when the fuel is up and the motors running.
​Take the ball out of the system.Then hook it direct to the pump without any thing in the line.
