I have a 2007 bf 50 on a hewes 180 sportsman. have not had it out in 3yrs due to illness.. changed oil and gear oil, new gas. cleaned bugs from all airlines. [oregon gets these little wasps that clog them].. when in neutral runs excellent. carbs sound great. when I go in gear, just as, and after the clutch engages , kinda loud rattle, but then powers up no prob. power down to idle and it does it. like a shaft is wallered out. I'm sure that is not whats happening, just sounds like it. any help would be appreciated. thanks...dave
