I am new to this forum and looking for some advice on a strange problem. I have a 1989 Merc 9.9 2 stroke on a Bass Buggy Pontoon. The engine runs great when it will start. Sometimes it will start perfect for days or even weeks. Then suddenly, I have no spark at either cylinder. Come back an hour later or the next day and it is fine. The problem only seems to happen when it sits for a week or two. Other times though, it can sit for a month and fire up fine. Any thoughts on what I can check for? Like I said, once it starts, it runs great, no issues. Thanks in advance!<br />Rob
