[yoggii]

I have a 1984 35 hp merc..I have cleaned carbs,rebuilt fuel pump,flushed out lines and tank,and it cranks good ,takes off good,runs good,for about two minutes and then just quits,cuts off..cranks back up if i pump the ball and runs another minute and quits again..sounds lie fuel pump but I rebuilt it. any ideas??

Re: merc stalls

I think something may be wrong with the check valves in the fuel pump,they are on the right sides because it runs good untill it quits,are they supposed to be tightened down tight,or supposed to move around??

Re: merc stalls

got it fixed,,check valve was bent causing spring not to work,,,runs great now..
