Starting and idling problem

[CanadianZ]

My Mariner engine runs very strong but I have noticed a few starting problems and sometimes it doesn't want to idle. I have to start the boat in neutral with a bit of throttle to get it to go otherwise it won't start. Also, it usually idles out if I leave it idling for more than 30 seconds or a minute.<br /><br />I have heard I should turn the adjustment screws on the carbs (three of them) a 1/4 turn. I have also heard I should adjust the throttle cable at the engine to give a bit more throttle at start up and at idle. <br /><br />Any ideas or suggestions much appreciated. thanks.<br /><br />Tony

You may also need to replace the restrictors. part # 66517<br />Should be 5 of them<br /><br />TMD

What are the restrictors?? Are they in the carbs?? Thanks for your help. I am trying to learn everything I can. Just my first boat.<br /><br />Tony

Re: Starting and idling problem

The restrictors are located under the intake ports on the side of the engine under your electronic parts.<br /><br />They let excessive fuel bleed down from one cyl to the next. If the restrictor is damaged or gone it will flood the cylinder below it at idle.<br /><br />TMD
