I have a 1985 Johnson 4hp made in Belgium and there is no spark coming from the bottom plug, top plug sparks fine.
What part or parts do i replace in order to get the lower plug to spark/fire? It turns over but does not start.
Any advice is always appreciated. mdl# J4BRHCOB

try swapping the bottom coil to the top, just to see if the problem follows.

You can get some wonderful guidance in the Top Secret File, under "universal magneto troubleshooting".
