The engine is a 1975 Mercury 1150 (115 hp) in line 6 2-stroke. I have appearantly caused a very bad thing, the engine was running a little rough this year. Cleaned the carbs and changed the plugs figured i would check and change the cap and rotor. As I'm sure most of you are aware that thing is built on there, well it's not on mine anymore. Any help on finding a replacement and how to replace it would be greatly appreciated.<br /><br />thanks in advance for any and all replies.
