I believe it is a 7261 because it came with a bagger. and it is a d600 motor because starter says d-600. All I need to do is put on a new recoil spring. It runs good. Any tips on putting recoil spring on? I have not gotten spring in mail yet. I have two d-600 starters to put springs on I will be selling one when it is done. tks very much for reply
