Mercury 4HP 4 Stroke Air Leak

[ChrisE]

I have one of the early - 1999 - 4 stroke 4 hp Mercury engines that had the seperate gas tank.<br /><br />Unfortunately it has developed a problem that I think is an air leak but I can't find it. At over half throttle the engine runs fine but as soon as I get below that the engine wants to run for a couple of minutes and then dies unless I squeeze the bulb a couple of times when the performance is repeated.<br /><br />Has anyone else had this problem & if so where was the air leak. <br /><br />I have checked the fuel pump & it seems to be OK.

What have you done to check air leaks?<br />What have you done to check the fuel pump?<br />Typically air leaks occur at tank and motor connectors May not leak gas just air.<br /> Also check any filters.
