I have been having a hard time getting my 1991 johnson 225 to start and finally went chasing down problems. What I have found is that there is a spark on 5 and 6 but not 1,2,3and 4. The plugs, wires and coils are all have about 15 hours on them. <br /><br />I did take the lead (power pack to coil) from a plug with park and move it to a plug that did not and got the plug to spark. <br /><br />What could make it so a power pack delivered spark to only 2 of six plugs? Is it likely to be to power pack or stator?
