I recently re-spooled my reel. The first time I spooled it was the first time I had spooled a bait cast reel, so I assumed that the line accumulating mainly on one side of the reel was just due to an error on my part. Now that I have done the process a second time I have run across the same issue. The spool of line is not level across the reel and tends to favor the right side. More line on the right side, less line on the left. I'm curious to see what I can do to fix this or if it has no effect. Thanks again!

Without seeing it, it is hard to say for certain. If just slightly built up on one side, it might be due to the way you are spooling the line, especially if the spool or your fingers holding the line are preferential to one side of the reel. If the difference is rather pronounced, it might be that your pawl that runs on the worm gear (moves your line guide left and right across the reel) is getting worn down. When this happens, it tends to not catch the tracks in the gear as well, especially on the far ends of the worm gear, and will frequently hang to one side or the other for an extra set of revolutions, resulting in a noticeable buildup of line to one side of the spool. If that is the case, you might be able to shim the existing pawl up a little to get better tracking, or simply replace with a new pawl.

Just the first 2 times you've spooled it. So is it new and you relatively new to casters?  It's probably just in need of you making sure the spool is centered in the frame using your cast control knob. Plus when you spool it up you need to watch and feed the line with your other hands fingers to feed the line. I usually have to sway the line in the  other direction  than the levelwind is going while spooling up with my home made winding station. Using your eyes to keep sure it lays even side to side.

If its a new reel then exchange it.  Sounds like you have a pawl/worm gear issue.  I've had new reels do that and I just replace em.  If it continues to do this then I would return it.  

Almost always,  it's your finger not centered in the spool.  Try not just making sure they're centered but,   move them a little further down the rod away from the reel.
