Re: Sound like bad bearing to you??

[chris-p]

I had to watch it a few times to hear it, but eventually did. Sure does sound like it from the video, but hard to tell. Is there any forward/aft movement of the flywheel?

I am just buttoning up a rebuild of a ’61 18hp with the same problem. Both upper and lower bearings were shot! Found the recirc line completely plugged up, I would have finished today but realized I don’t have any little fuel barbs to install to replace with the original with new. My project also had a bad bottom carbon seal, and missing drive shaft o ring, letting water into the bottom bearing.
