Crmaverick 91 #1 Posted December 28, 2020 (edited) I went to replace the prong style spark plug connector on my pull start K161 to a rubber boot push down. The one I ordered here doesn’t fit the small wire gauge. Does anyone have a part number or know what style I would need? Is this the style that works the screw one type? https://www.ebay.com/itm/NGK-LB05EP-5k-resistor-spark-plug-boot-cap-cover-snowmobile-atv-motorcycle-/222391571174?_trksid=p2349624.m46890.l49292 thanks Edited December 28, 2020 by Crmaverick Edit Share this post Link to post Share on other sites

On this pull start style the coil is fused to the wire, so I’m just looking to replace the connector at the spark plug, I didn’t see any from them but I would think this is a pretty common thing to replace.

squonk 41,164 #5 Posted December 28, 2020 (edited) I'm looking at your picture. The wire end looks correct for the wire you have pictured. You are supposed to fold the bare wire back over the rubber insulation. Then put the non crimp side of the connector over the bare wire and insulation and crimp the opposite side ( The open end ) to the wire insulation. If you have a Napa near by I can give you part numbers. These pics here I am crimping on a coil terminal but the plug end is the same. Silver spark plug connector is Napa 727006 Boot is 727402 Edited December 28, 2020 by squonk 3 2 Share this post Link to post Share on other sites

Also is there any special crimp tool or do you just fold those sides over and crimp flat with some pliers? Edited December 28, 2020 by Crmaverick Share this post Link to post Share on other sites
squonk 41,164 #7 Posted December 28, 2020 Special crimp pliers but they are like 50 bucks. You can see them in my picture. Regular pliers will work but you have to be careful. Share this post Link to post Share on other sites

squonk 41,164 #10 Posted December 28, 2020 Those aren't the right pliers. What you have there are the jaws to crimp solderless wire connectors. Plug wire crimpers are bigger. Those pliers will mash the terminal. After the end is crimped, use lots of silicone spray and slide the terminal into the small end of the boot and push until it appears at the plug opening of the boot Share this post Link to post Share on other sites
