I'm still working on a Stihl 046 and think I may have zeroed in on the problem with weak spark. We ordered a Stihl ignition module part number 0000 400 1300 which I thought at the time would work. I think the correct number is 1122 400 1314. Does anyone know the difference between these two modules since they look identical on the outside..This saw has the plastic flywheel fins..
