I while back I made a post about how my BN6 would sputter (miss) when holding a steady speed and occasionally backfire during decel, yet run smoothly when accelerating. Yesterday I checked the timing using a timing light (purchased from Moss) that has an advance dial. Turns out the timing was advanced 34 degrees! So with the aid of my timing light, I adjusted the timing to 12 degrees advance (my BN6 has a BJ8 head & cam). Problem solved, now she runs great! I was all set to mess with the carbs, glad I started with the easy fix first.
