I like being more proactive so that's why I do certain things as a precautionary measure. Perhaps I'll do things a little differently from now on.

As it is, the wristpin is as clean now as it was when it was new. I'll was just going to clean it out and run it, but The rear bearing has a metal retainer. ( this engine was made in the early 90's.) I will need to remove the hub to pull the crank in order to replace the bearing. This engine is getting a Jett stream muffler and it set up to scream. I don't want the bearings to explode. Should I just run it as-is or pull it apart and replace the bearing?
