I have a 1986 Johnson 4.5
If anyone can offer me any thoughts or suggestions I would be most appreciative as I have been troubleshooting this motor for a few weeks now.
I can get her to turn over and run after repeated tries of pulling. Once I get her running she stalls out at high speed and low idle. I noticed that I am only getting spark from one of the spark plugs (the one on the bottom).
When I first received the motor it just backfired until I swapped the spark plug wires (I figured the previous owner just had them on the wrong plugs)
My hunch is that either I have a bad coil or power pack.
Seeing how I have a spark to one plug does this mean the stator is good?
I tried testing each coil with the light bulb test, but was not able to get either coil to light the bulb when I cranked her over.
Is thier another test that I can perform on each coil to see if they are working?
Is thier a way I can test the power pack?
I noticed that I have continuety on both coils when I touch both of the wires comming out of the coil. Is this normal?
Also is thier a reliable place to purchase Johnson parts that has a return policy on parts if I end up not having to replace both the coil and power pack?
