If I'm not mistaken, there are three different Elasto-start sizes. They all share the same part number, the only difference being cord diameter.
0000 190 3402 (example application ms 250)
1128 190 3400 (example application ms 361)
1122 190 3400 (example application ms 600)
these are the three that i am aware of (and probably the ones you are talking about). there are no two different stihl parts which share the same part number. also, the replacement ropes are available with the elasto-start necessities present on the rope, just put new rope inside the handle.
