Harrison won't do it? Huh. I guess David or Vince didn't feel like messing with it.
He was always my "go-to" guy, but I guess if he doesn't want it, you may have to go elsewhere. There is a reasonably good shop in Marietta called (reasonably enough) CARS, they did a bang-up job on my fuel tank / pump / sender.

They are the techs from Flashback Motorworks after that place closed overnight a few months ago. Steve Curran is the gent to talk to, and their phone is ( 678 ) 402-5680. They have done some work on other coupes, as well as many older Jags, so I know they have carb experience.
That said, I don't remember seeing another coupe rolling aroud the Alpharetta area when I was there more regularly. When did you pick it up? My coupe is still there, all garaged up.
