What do you think of this plug?

ah, yes ... i too have to chime in...i run champions in my lawn mower only, they suck. ran a high volume shop in florida for 15 yrs. I always used autolite, or ngk. never had a problem with them. the tan color on your electrode looks good, white would be better, but with all the additives in todays gas, tan is all your gonna get. right heat range plug, good air/ fuel mixture settings. leave it alone...
