Isn't the Onan running wasted spark where both plugs fire simultaneously even though only one cylinder is on the power stroke? Both plugs have fire in order for the motor to operate.

Mine Onan quit running. I checked the plugs and one was not firing. I tried to check the spark and it did not jump even when almost touching. I took hold and one spark was almost none existing. The other one let me know it was there. I had a spare coil and hooked it up. Still did not get a span to jump but when I took hold of it both let me know they were there. I install the plugs and it started. I still wonder if the spark should be strong enough to jump when I check it. I put a screw driver into the used it to jump to the block.

How does the coil come off the 7kw unite. It is hard to see in the back of the unite. I just wired the coil in and now need to replace it. The coil came off a 4 kw unit I have stored.

I was worried it was my rigged fuel pump and filter but it was not.
