      This is a linear taper pot and I made sure I got it clocked correctly   
     before I locked the cog pulley down . I have another , I'll check   
   resistance values tomorrow .   
      The original pedal broke the pot because the overtravel stop screw   
   was missing . I repaired and used that pedal for a while . I asked   
   Everlast customer service for a replacement pot and they sent me a whole   
   new pedal - which is the one I just repaired . The old one still works   
   and is here somewhere I put it so I'd remember where it was ... but that   
   was 12 years ago , and my memory is the second shortest part of my   
   anatomy .
