90 Hp Force Fuel Issue

[57wplman]

I have a 90 hp force that stalls out after warmup going to WOT. Not sure if it is flooding out or starving for fuel. It will easily restart and if you slowly go to WOT it usually will run ok. Have checked spark plugs and firing. Have replaced fuel line and bulb. Any thoughts are appreciated.

Re: 90 Hp Force Fuel Issue

Try squeezing the primer bulb at the same time you quickly go to WOT. If that helps, then it's probably starving for fuel.

If it does help, makes sure the gas tank vent line is open and not closed or blocked. Make sure you don't have any blockage in the fuel line or pick up in the tank itself. Replace the fuel pump diaphragm. If you have the older fuel pump that kind of looks like a figure eight, replace the 3 check valves too. The newer square type normally has the check valves as part of the fuel pump rebuild kit.
