Yes. I did this. As soon as the noise started I stopped the engine. Restarted it and went to a dock
20 yards away and popped the cover off. I was looking to see if sonetbibg had come off the pull start mechanism as that's where the noise appeared to be coming from. And both in neutral and in gear
But by the time I got it to the mechanic 1/2 mile, 15 minutes later the noise stopped.
The mechanic said he could hear bearing noise. But I couldn't hear it then.
I then went about 1nm slowly and didn't get the noise back.
