Personally, I would not use a Champion plug. Go to a cross reference chart and get the NGK equivalent. While "back in the day" Champion may have been the standard plug to use, I am now doubting that they are made to the high quality specs they used to be. About 5 years ago I starting getting "duds"- these were brand new, right out of the box plugs. After I switched to NGK not one single dud. Also, I started to look at what plugs professional small engine parts and repair shops were using in my area- every one was using NGK. That tells me something right there.
Just my .02 cents...
