1987 Force 125 no spark on 1 and 3 cyl. Please help.
I have a 1987 Force 125 h.p. that is not sparking on the 1st and 3rd cylinder. I checked ohms on trigger and stator. They checked out O.K. I replaced switchbox and coils for 3 and 4 cylinder with no luck. When I switch the wires 1 and 2. 1 sparks and 2 no spark. When I switch 3 and 4. 3 sparks and 4 sparks. I must have multiple problems cause I'm lost . Help is greatly appreciated. Thanks
