1984 Johnson 115. Gas slick after engine shut off

[WaterBeetle]

I recently purchased our boat and I notice that after we shut the engine down, there is a gas slick (smells like gas) in the water. It doesn't last very long, but gives a slick of a couple feet radius.<br /><br />Is this normal?

Probably not. How does the engine run?<br />1.Look for loose connections at the fuel line engine connector or leaks in the fuel line.<br />2.Check for stuck open floats in 1 or more carbs.<br />3.Check for leaking (internally) fuel pump diaphragms.

The engine runs great. I had cleaned and rebuilt carbs earlier because of a rough idle (wasn't the problem at the time, it was rotten fuel lines).<br /><br />I'll do the other checks. Thanks.
