You can do it yourself. Manuals are available. Look for the Seloc manual... If the parts are in good shape, you sould probably build it. If it needs some attention, it may be best to bring it to a pro. Tell us where you are at and I bet someone can name a shop close to you who can do the work...Pics always help. You could get a good diagnosis here... What speed did it run, RPM? I could open up a can of worms and ask you what your speed plans were...
