Paul Abbott who owns Performance Oriented has announced that he is interested in selling the business. He is in Salem, Oregon and has long been known as one of the best Weber restorers and blueprinters in the business. It will be a loss to the triple throat Weber community if we lose this resource. Sounds like he is going to retire. I had my 46's done by him about 10 years ago and they were perfect. Among the many services he provides; he replaces the bushed ends of the throttle shaft which wear and leak air (causing popping, mixture problems and tuning difficulty) making for a super smooth operation. I hope someone with similar talent will follow on.
Paul has a quite a resume - mechanical engineer, design engineer and VP of engineering for General Dynamics. Long time Porsche owner. His web site has loads of valuable technical information.
