    Rough idle trouble giving it gas

    Johnson 200 j200plsif
    starts fine runs rough. If you start it and hit thee throttle right away it takes off and runs great but let it idle it chokes out when you try to give it throttle. Any ideas what could be causing this. I replaced the fuel filter and the vro.
    thanks for any info on diagnosing

    Check your throttle roller and see if the clear sleeve is still intact.

    Yes syncing the carbs with the timing of the motor. If you don't have a manual and timing light take it to a dealer. From your picture you are way off on your idle timing.
