    2007 stx 12f engine races on start up

    I replaced pistons and rings and assembled. On start up the engine raced instead of idling. The isc sounds when the engine is stopped and has the correct ohms reading on the pins. What else controls or affects the idle? What else should I check? Thanks,

    Throttle cable adjust incorrectly..
    Check to ensure blade closes fully

    Gday, I am a novice at this. Could you give me more detail about the blade, where do I look to check and what am looking for? Thanks

    when you remove the intake tube from the THROTTLE BODY the disc in side should have basicly no gap around the out side ,
    or look at the idle set screw on the T?B near the cable the cable holder should be sitting on that.....
