Levelwind not so level???

All suggestions are correct. If the reel has been doing that since it came out of the box, it sounds like the spool is not centered. The 6500 has the spool bearings in the spool itself. On one side there is a fixed bushing and on the other side there is an assembly that holds the shaft that holds the spool. Under each is a copper colored shim or two. The only way you can shift the spool is by taking a shim from one side and putting it on the other side. That is the only spool adjustment available on that reel. My feeling is that either the worm or the pall is giving you trouble.
Also if you are reeling line in and holding the reel cocked to one side it will also cause the line to load on one side unevenly as you describe. Are you cleaning the worm and keeping it lightly oiled? No grease on the worm or pall!

Thanks guys. Definatly not scared to tear abu's open. A few years ago one vomited on me and it took forever to get back together. They are wicked easy to work on. I will look for the things you guys mentioned. Gotta do it soon for that big wave of cows that are coming

I have spooled abu's with fresh line and noticed this happen. I found the cause to be the tension I placed on the line while spooling. Not enough tension sometimes leads to backlashes. My problem was running the line through my fingers and onto the reel, holding the line close to the reel and off center, it packed up on the side my hand was holding the line on.
