I recently purchased a 1993 pontoon boat with a 1993 70hp force engine. The previous owner said that the last time he ran it, it ran rough.<br /><br />I could only keep the engine running at over 1,000 rpm with partial trottle baffle, dies in idle position. To much fuel.<br /><br />Pulling the fuel pump off, i found that there were several holes in the diaphram. I replace the complete fuel pump and gasket and installed a complete new carburateor. Still having same problem...to much fuel at idle. I can take the recirculation hose off from the top of the reed block and it runs a little better for a while.<br /><br />I have pulled the recirculation block off and have inspected the reeds, no problem found.<br /><br />Can fuel be circulating into the engine for another source? Vaccum/<br />check valve?<br /><br />Need some ideas?????
