The video makes it sound horrific, but it's really quite quiet. There's just a couple ticking noises that aren't very consistent that I can't put my finger on, does this sound healthy to you? Just synced carbs and adjusted cam chain tensioner, (I adjusted it by first taking it apart and cleaning/lubing it, then put it in, wound in by fingers until felt resistance, then backed out a full turn, started engine, wound in with fingers until tight, and backed out 1/6th turn, and tightened.)
