Hello everyone. I have acquired two 1498's. One is a 1950 model, and the other is a 1970's DA model. Neither reel seems to have been used. I replaced a spring in one and added the One Pfoot drag plate to the older model to switch from RHW to LHW. After the switch, I noticed that there is a skip in the drag about every 8-10 clicks. This only happens when the drag is tightened. When loosened, it does not skip. Any idea why this might be happening?
