Help with PENN 2000 Speed Shifter

I have a PENN 2000 Speed Shifter baitcasting reel that I purchased around 15 years ago.  It is a two speed reel, and shifts from high speed 6:1 to low speed 2:1 depending on your setting of the speed shifter.  I like it for crankbaits, especially for fighting the fish when it shifts to the lower speed after setting the hook.  The problem I have is the 10 lb test line that I like to use for crankbaits has always got caught between the spool and the housing on either side of the spool.  I've gone as high as 14 lb test and it still happens.  There doesn't appear to be a noticeable gap between the spool and the housing. I can't figure out why it has always does this.  Does anyone know if this problem be fixed or repaired?  I know I didn't spend a lot of money for it and the quality isn't the greatest, but I like it matched up with my fiberglass 1960's Silaflex Magnum that I had redone (yes I was warned what would happen to the value, and I saved that unique handle). Thanks for any info.
