After doing some more searching, it appears that the ignition wire connector needs to be crimped via some tool made by Baum, after which the connector can be screwed into the spark plug connector. Is the Baum crimper a special tool, or can I use "any" crimper? I would appreciate it if someone could post a picture of a crimped wire end so I can figure out if the local electronics shop has something that would get the job done. Thanks.
