Spark Plug

Black is rich,(running cold),white is lean(running hot) tan is nice. Try adjusting the pilot scews (this is air fuel mixture scews). Thay should be set at 2 1/4 turns out to start whith, you will have to run the machine on a good ride and recheck the plugs. and then readjust the pilot screws untill you get right. Good Luck.

 

It is a bit rich, but your photos are going to be hard to read also. Try coning in more and using a white background.
