A few days ago i noticed a little oily mixture on the balancer ring behind the prop,today when i was messing with it,i thought i felt a mist while i was standing in front of the prop so i gave it more throttle and yep,there was a light misting,later when i shut it off i noticed at the base of the carb had fuel around it,i'm wondering if it's coming from the top of the carb or is there a seal on the front somewhere ?,also,how does that black ring come off or is it threaded ?.The engine is the Evolution 61.
Thanks
