Define nickle and dime LOL
I have seen these old girls last beyond 100,000 miles before anything really major--but it's always little stuff isn't it. I yanked my OEM petcock off and put a Pingel on and it definitely flows fuel much better--and I have had it since 1996. If you are going to keep it a while longer then why not use a Pingel over the OEM? That way when it needs a rebuild, you can get a rebuild, and not have to worry about buying an entire assembly. That is if you plan on keeping it--if you plan on parting ways in the near future then I would try also to replace with minimal investment.
