i am almost finished re-biulding my 90hp johnson and have relaced all of my fuel lines and now I amm checking spark on all of the coils. I am only getting spark on two out of the four. One wire was bad so that ruled out a faulty coil but the other I cant get spark on. I am going to go ahead and replace all of the wires to be safe but what I need to know is if and how I can check all of the coils for spark and if so if it is adequate. once again how can I check each individual coil? any help is appreciated.
