Repair Clinic and E-Replacement Parts have parts. E Replacement Parts has exploded views of equipment. Stens has a FULL-LINE catalog for ALL kinds of 2 and 4 cycle equipment. It is a VERY good catalog! Amazon has it. Get Amazon's 12" hemostat pliers or the 45 degree hemostat pliers to replace fuel lines. Cut lines at a slant to ease installation. Work them back and forth to loosen. Set the lo mixture for highest RPM's at idle and hi mixture for highest RPM's at full-throttle. Set the idle just until the chain just stops on a chainsaw.
