I posted earlier about my CV16s2 running poorly. I was certain that one of the ignition coils was bad and I received a new one today and put it on and now it runs fine. I did notice something though that I don't think is right. I installed the new coil the same way the old one was but I noticed that the coils are rotated 180 degrees. In other word the kill wire terminal is on top on one cylinder and on the bottom of the other. I am not sure why they would be installed differently and also not sure if it matters. I am trying to find a picture of the engine with the shroud off to see if the coils should be mounted the same direction and which direction is correct. It does run as is so maybe it doesn't matter.
