Johnson J115ELEOC has run fine but this past weekend I took it out and after a few minutes of running noticed a loud "rattle" sound coming from the engine. Shut it down, and it started up just fine, but I can hear the noise at idle, and at all speeds. At low RPMs the rattle is slower and increases in tempo with RPMs. Might have been a little low on power (felt like it was surging a bit), but other than that loud rattle noise it seemed fine. The way it sounded I guessed that something was hitting the flywheel on each revolution, but I am no mechanic!
Any suggestions what might be causing this noise?
