I am new to this and just stumbled across your forum... <br /><br />I am having troubles with my motor 93 Marinier 15 HP. I borrowed it to a friend and this is the way i got it back ... There is a whirling noise when I pull the recoil that was not there before and when it starts it sounds like bad lifter on a car motor only louder sounds like it is coming from the back of the motor or lower end ???.... Any idea where to start looking ... i am a newbie at this so be easy on me !!!!
