All of my reels do this.
But I came up with a solution a few years ago that has been working so far:
- make sure initial new line is tied in the center of the spool
- if using right handle reel, ensure the line guide travels toward the right first; if using a left handle reel, the line guide should start traveling left first
- adjust spool tension to how you will fish on the water
- adjust brakes to medium or what settings you fish most with
- adjust drag to where you think you fish most with
- use lots on tension on the donor spool until about half way, then medium tension the rest
- pay attention the how the line is stacking; if it is higher on the left, move the reel to the right of the donor spool until it is even; stacking to the right, move reel to the left
I think the key is to get a good even lay on the first half of the spool because that is what the fishable half uses as a base. If your base is uneven the top half will always reel back on uneven.
