Quick shipper. Good people to deal with. You guys should let people know that if they’re converting their MS260 from the worm drive to this type of oiler, they’ll need Stihl part number 0000 958 1234 Washer and part number 0000 993 0508 12X15X12 Ring to complete the install. Or perhaps add it to the kit and tack on 10 bucks to your price. THANK YOU!
