I have a 1996 225 carb engine that the flywheel bolt came loose on and engine would not start. I pulled the flywheel and found that the key had broke, ordered two new one's. Installed the new one and engine started, but runs very rough, i take it that the timing is off. The manual i have, states that the maximum spark timing is controlled by the ECU and is not adjustable. Can someone please walk me thru the process of what to do. The engine ser. # is OG243354, if that helps. Any and all advise will be greatly appreiciated. Thanks Mark.
