I have a 1987 20hp Evinrude that misfires. At least I think it is misfiring. It doesn't happen all the time, it can go weeks without having this problem but I caught it on video this time. Also when it is happening it will be more pronounced when the engine has been running for a while. Here is the video link https://youtu.be/5SSmcnzCE94 In the video you can hear a surge and see the engine move a bit. Any help with a diagnosis or a fix would be greatly appreciated.
