    I have a redmax ebz5100 back pack blower. The other day went to replace the spark plug and the spring that sits inside the spark plug cover that is connected to the spark plug wire came off. Do I need another spark plug wire assembly. Any help would be greatly appreciated!

    Thanks in advance


    • Hi Steve!

      While it is probably easier to get a new ignition assembly, you could remove the spark plug boot from the wire and see if you can figure out how to re-attach the spring, if it is similar to other lawn equipment ignition wires you should be able to push the ends of the spring into the insulation of the wire so that the spring is sitting on top of the wire, and then you just slide the spark plug boot back on over top (every piece of equipment is different, and I’m not exactly sure how the Redmax leaf blowers are set up). If it is looking like it won’t be a very sturdy hold, or that the wire is damaged, I would recommend going ahead and getting the new ignition assembly!
