    Default 1999 50hp Johnson wont run

    I have a 99 Johnson 50hp that wont idle unless you push the primer all the time also wont throttle up just dies. I have done a sync and link a compression test a fuel pressure test and rebuilt the carbs also replaced a damaged reed valve assembly, anyone have any help or ideas would be greatly appreciated.

    Carbs need recleaned with kits.
    How old is the gas?
    How clean is the gas?
