My recent Blitz kart purchased

[Richard Stamile]

   
Hi Guys
    i just acquired a Blitz a friend found at a yard sale  i just removed the rear axle brake and
   wheels  so its not in the pics but came with the kart, my question is the rims on 2 of the wheels have some of the edge
  broken off some g0ld color is left on one of them  are they aluminum? and can they be repaired like they do with
  the car rims  or not worth it just find good ones  the pan is a mass i plan to have a shop make up a new one and
 i do TIG  fixing up the rest of this isn't a problem  as a kid living on long island with not much money i always loved
 these i remember drooling over another kids brand new red Blitz that his Dad bought him  i remember him says it
 was a Blitz demon  don't know how that the demon differs from any other model they made will post photo's of the
project
