Hello all, I have a 120 Johnson thats not firing on two cylinders ( left top and bottom). I've done a compression test and it's 125 on all and also a carb rebuild. I also ran it off a seperate fuel tank into the VRO and replaced all plug wires. It won't plane off and is only running and 1/3 under load and is sputtering. I have someone else driving it when I pump the fuel bulb and its the same result. It's when I did a spark test yesterday when I found the no spark issue. What would be causing the no spark?
