The saw would make some horrible noises, blade seemed to be running true yet the noise would come and go. Thought that there may be some strange harmonic thing going on. Took the belt cover off and discovered the key was loose in the shaft holding the pulley on. Here is a shot of the damage to the cover: Whew!

The key should be long enough to fit completely under the set screw. Take the set screw completely out. Drive the key in until it's flush with the outside of the pulley, or as far in as it will go. Put a dab of non hardening locktite on the set screw and tighten it down. The problem should be cured.
My Covington 16" used to do the same thing. Even had to chase a pulley down the driveway a couple times. Since using the locktite I've never had the problem again.

Just like Don said using the PROPER locktite for the job is a great suggestion. I hesitate to mention this because some people don't know there are different types and use the normal stuff. This causes a whole new set of unpleasant issues LOL. Proper torque on the set screw will do the same job. Anyway it does not sound like a huge problem with the saws, but a bit of PM might save some trouble later. By all means get a small bottle of NON HARDENING locktite, make sure is its the stuff used on threaded components that can be undone again.
