MoriaRiverMan Posted April 27, 2008 Report Share Posted April 27, 2008 Got boat out today in river.........great to see it almost back to normal levels I thought the boat had a carb issue but seemed great today...........at about 25% throtle it does loose all spark it seems for about a sec.........then fine for 5 sec and then looses spark.......... Runs like a champ at WOT and IDLE.. Any idea's? Spark plug gap maybe?? They are bran new. its a 91 or so 20HP evinrude. Thanks Derrick Link to comment Share on other sites More sharing options...
danc Posted April 27, 2008 Report Share Posted April 27, 2008 I doubt that it's losing spark. A gummed up carb would be my guess. Link to comment Share on other sites More sharing options...
MoriaRiverMan Posted April 28, 2008 Author Report Share Posted April 28, 2008 any easy way to check fuel line? Link to comment Share on other sites More sharing options...
Sinker Posted April 28, 2008 Report Share Posted April 28, 2008 Yup, sounds like a fuel issue to me. Check your fuel filter/lines. Something is blocked or sucking air by the sounds of things. Sinker Link to comment Share on other sites More sharing options...
