I initially thought it was the power pack as a whole side of my 81 Johnson 140 would have no spark. I would move the power pack to the opposite side and that side wouldn’t have spark. I replaced the power pack with a new one and still had the issue. I ended up today replacing the timing base and stator (they were used) and now I have spark on both sides but no spark on cylinder 1 and 4 (diagonal to eachother). What else could be the issue???
