The 1135 400 1300 ignition module was delivered with (ignition module, grommet and ignition lead (195mm). You also need the insulating hose (110mm) 1117 442 0905, the torsion spring 0000 998 0604 which is pressed into the ignition lead and the spark plug boot 1128 405 1000. Push in the torsion spring in the ignition lead, about 15mm from the end of the lead.

Here is a snapshot of the module and the parts it comes with and the ones I`ve descriped you also need.
DND...... First things first, thanks ever so much for the schematic drawing showing the complete Stihl 1135 400 1300 Ignition Module Assembly.
Okay, so I've now received Stihl Item No. 11354001300 and, as DND 9000 so wisely pointed out, the ignition module itself comes with a 195 mm Ignition Lead and a Rubber Grommet attached to it. As the drawing supports, the Stihl part number for those two (2) parts is as follows: 0000 989 1002 (in case you don't get them with the module).
I'm assuming that the 110 mm Insulating Hose (Stihl 1117 442 0905) is a protective cover for the Ignition Lead. The Spark Plug Boot (Stihl 1128 405 1000) is self-explanatory, but the Torsion Spring (Stihl 0000 998 0604) has me a bit puzzled. Judging by its nomenclature, I would venture a guess and say that the spring gets pushed into the lead end of the spark plug boot until it stops and, after that, the spark plug boot is pushed over the free end of the ignition lead until the spring "clamps down" and effectively grips the ignition lead. Is that a decent guess or, conversely, does the spring go over the ignition lead first and, after the spring is in place, the spark plug boot gets pushed over the top of the torsion spring? As ever, thanks for your time.
