Cuts off at idle (video of offending motor included)

[phatdaddy]

on my carbed merc, when the fuek pump was getting weak, i would notice it when trolling. the motor would start dying. i could run back and pump the ball a few times and it would pick up and be ok for a while. next time it starts to stumble, try pumping ball.

like skunk said, video sounds like u cut the switch off

When the pump fails they normally stop pumping, leak fuel into the crankcase from a ruptured diaphram, or leak externally. If it was a weak pump, you'd have to go back and pump the primer bulb to restart it.

I agree, not the best video. Just before I started filming it really showed it's @ss. I do have to sometimes squeeze the ball to get it going again. I think I'm gonna replace the fuel pumps ($100) and see what happens. I've paid more than that for a diagnostic fee before Appreciate the replies, will keep you guys posted on the outcome.

you probably already know this but....make sure the arrow on the ball is pointed UP at the motor.

Have you tried pumping the primer bulb while its running? This would basically be using you/the primer as the fuel pump. I just rewatched the video and it sure sounds like a lean sneeze to me that shuts it off.

Ferm, I have tried squeezing the bulb, but it has been a while and best I can remember I had mixed reviews about it helping to keep the motor running. Can try again and report back

Let's say I ruled out fuel pumps and suspect lean sneeze. What would the remediation steps for such symptoms?

Pull the carbs, pull all the jets, soak them, clean them them, and put em back together with new gaskets & seals.
