Evinrude Outboard Idle Problems

[Husky2006]

I have a 1991 8 HP Evinrude that ran great for many years, but has recently developed a low idle problem. It runs fine at a higher RPM, but won't stay running at low idle. <br />Gas is clean and right mix. <br />Gas line and fuel pump filter are free and clean.<br />Could the fuel pump be going bad? Any way to test the fuel pump?<br />Is there a low speed adjustment I could make?<br />Does anyone have any other suggestions on what is causing the low idle problem?<br /><br />Thanks

Before you give up you might try a decarb as explained all over this site. I thought, as you, that I had all my ducks lined up, but idle was rough and couldn't find any cause.<br /><br />After decarbing (I use the addition of Sea Foam to the gas) over the last couple of months and the engine idles much smoother; starts easier, and restarts quicker.<br /><br />Might want to try it before you start tearing things apart.<br /><br />Mark

Texasmark,<br /><br />Thanks for the decarb/Seafoam advice. I will give it a try.
