Hello,, looking for some help I have a outboard 70 hp johnson that fires on all three cylinders when cold, Once it warms up,, i loose spark on cyl 1 and 3. I replaced the power pack and it made no change, I tried testing it per the manual but seems a bit confusing, I tested the stator and it failed, and then passed once cooled off, Has anyone ran into this before or can offer some advice, The only other part was the timming base.but since it fires when cold, i dont think that would be the issue, any help ??
