Who can read this plug, I don't know if its the same for cars, or what exactly to look for. This has 124 main jet, 2 3/4 (roughly) idle mixture screw turns, no snorkel, stock header with slip on. Too lean? Too rich? I personally think its about perfect, but I don't know about that black ring on the outside of the electrode

You rock thanks

 

The sooty threads are from idling rich,probably with choke during warm up. Once your up and running the soot burns off the hot tip and strap.Looks good to me

The thing is I haven't been using the choke at all
