On the cylinder that isn’t producing spark, It is very important to have the fiber and metal washers in the correct order and location on the 2 bolts securing the coil to the head. Check the coil ground also ,disassemble and clean the bolts, washers and ground terminal,and look for a broken or corroded ground wire. Clean the coil and its ground tab.
Check that the spark plug spring terminal is not corroded and pierces the spark plug conductor.
Inspect the wiring from the power pack to the coils,flex the wires by moving the throttle as you check with a meter for continuity.
Anyone have a shop manual showing the correct sequence for the washers on the coils, and if so could you post the diagram. I was told it is very important,the manual also states so and has a close up diagram showing the washer type and position.
Thanks Johnnyrude200 for being clear on the above when i was working on my 1989 9.9 🙂
