  • Yamaha 1998 40MLHW

    What is the best method to cleaning the 3 carbs on a Yamaha 40MLHW?
    How do you check to see if the lower unit needs more greaseing?
    How do you adjust the idle speed?





    Iam having such bad luck.After the carbs were cleaned and set back in.I gased it up and then took it for a test run and it ran for 45 minutes and then it slowed down and stopped and I tried to restart, and the pull chord was froze and could not be pulled ..........what happened?

    My buddy says to remove the spark plugs and pour some oil into each chamber and let sit,and then try to turn the propeller,and if it turns gently continue,and it should be fine........

    But what happened to have it do this in the first place?
