I go to Ashby Sewing in kennesaw, Ga. Mark use to sale Pffafs and still services them. There are some of the older models where parts are no longer available due the sale of the company a while ago. The small companies that made the parts closed when Pfaff moved the plant. He usually has most stored at shop or can do adjustments. It is located just across from airport in Kennesaw on Old Hwy 41. Have not had good success with the dealer in Duluth . This dealer also has an outlet in Alpharetta. Many friends have had good luck with the New machines with them but not repair work on older models. Mark at Ashby's will help you if it can be fixed. He's worked on all 3 if mine for over 15 years.
