      This British company has Champion R7,C7,D6and other hard to find sparkers. http://www.gsparkplug.com/ (Green Spark Plug). The oil recommendation of 3/4 pint per gal.and 1pint per gal for heavy use is what is stated in the Johnson service manual.

        Yeah – 1 pint/gallon is 8 to 1, while 3/4 pint is around 10 to 1.
