Mariner 4HP Outboard - Will not Idle

[Neil A. Runyon]

I purchased the motor five years ago. However, it only has ten or so hours on it. I cleaned it all up and put fresh fuel in it and it will start okay. <br /><br />But, it will not idle unless it is set at very high rpm. At lower rpm, it just dies.<br /><br />Any suggestions are much appreciated.

TRY TO ADJUST YOUR LOW SPEED JETS.

I'm an amateur. Can you tell me where the "low speed jets" are located? I have an idle screw and fuel mixture screw but not sure how one would adjust the jets.<br /><br />Sorry for the bother and thanks in advance.

Jets in the carb which are quick easy to replace if you get a manual. I have never worked on a carb before boy is it easy.

Hi, Neil. I think this is a duplicate,but. . . <br />Low speed jets and Idle mixture mean pretty much the same thing. What Rex is suggesting is that you richen the low speed mixture, back out the idle mixture screw a half turn or so. If that doesn'r do any good, you may need to dismantle and clean your carb, with particular attention to the low speed circuit passages. <br /><br />Red sky at night. . .<br />JB
