The reason the connection was so flimsy is that it was improperly installed and crimped. When you stripped and exposed the wire which was exactly right, you were supposed to then bend the wire back. This was where you went wrong. When you crimp the connector you must crimp it over the bent back wire around the end of the rubber insulation. crimping it in this fashion would of used all the space that was left over as shown on your demonstration. Crimping the wire bent back around the end of the rubber insulation gives it greater holding strength. Although your method would work, it would merely need some typical wear and tear pulling or snagging before it would pull from that soft metal on metal crimp and will eventually disconnect. The proper crimp around the outer wire rubber insulation and the bent back inner conductor metal crimped around the rubber acts as a natural brake, which will hold up against average wear and tear pulling and snagging, with no extra crimping material left over, and the crimp will be very sturdy, not flimsy, in fact when done properly the metal crimping material will perfectly encompasses the wire. Hope this helps!

Oh my gosh thank you so much been trying to figure out how to fix this I was going to cut a wire off the other lawn mower as there's no man in my life to help after watching your video I know now that I only need the boot and the clip thank you Jesus for your help

Short, sweet and to the point! I need to replace a corroded boot that has been out in the elements for some years, no longer makes a connection with the spark plug.

First time he cut his finger lolol😅😅😅😅

Good of you to post this video but you’ve done this completely wrong. Dave Annis is absolutely right. Strip the wire like you did, bend the open copper wire back over the cable end and fit the terminal onto that. Much stronger

This info is exactly what I was looking for. Thank you so much.

Thank you very much for posting, god bless you

very ,very helpful. Thanks!

Legend, thanks!!

The video was very. Helpful. .

Video. Came. In very handy,

cheers bro

Thanks man!

This video was great and I've now successfully revived my petrol lawnmower. Thanks!

I looked at my old one to compare.. metal end is rusty which is why I'm replacing it.

That's not how you do it. you fold the exposed wire back over the insulated wire and crimp the connector trapping the exposed wire between the wire body and connector.

Give up on repairing lawnmower son
