Last night I started doing my first conversion (SXLAO blue Prestolite armature into Husky Module) and ran into an issue.
The tear down of the Prestolite was straight forward, when I came to the China Husky coil, I saw that what I thought was a locking tab was imbedded in the potting material. I was about to cut this and press out the armature when I stopped and thought I would ask the experts. Can someone tell me if this is a locking tab or a ground strap. Also if it is not a locking tab, does the armature just press out of the module? Second question on these modules, did you shorten the 5 mm wire from the boot side or coil side? it appears that the wire is bonded to the coil side.
I found out the hard way that it's a ground strap.Be careful in removing the laminations,they don't press out very easily.Some of the Chinese coils have the wire glued in & others screw in.If yours is glued in remove the boot & spring,cut to the desired length & put the spring back on making sure it's centered on the wire to get a good connection,then push the boot back on over the spring.Mine pushed on easily,but you can use a lube of your choice if needed.

That is almost certainly a ground strap, necessary for the coil to work. It is usually a press fit, not screwed or soldered to anything but pressed against the steel armature.
You don't show a view of the flywheel side of the armature but sometimes there is a tab bent over there to retain the coil.
Homelite plug wires are generally screwed into the coil with a sealant applied to the joint. Since this is not a Homelite coil, I would shorten the plug end of the wire and replace the boot and terminal there. The terminal may be reusable, push the boot back onto the wire and see. I would not remove the boot from the wire as it would likely be damaged. You may find you can simply re-loop the plug wire to fit without cutting. Do not block a finned area on the cylinder with the wire, it could cause a local hot spot and damage.

I finally test fired my saw this weekend, after some carb tuning, it ran like a champ. I ended up designing a little Delrin fixture to press off the armature from the Husky coil, it worked great. I did not shorten the lead on the new coil, instead wrapped with heat tape and zip tied loop at the oil line elbow.
