I run Champion 516 D16 spark plugs on both of my pony motors. Does anyone know the proper gap for these plugs? Thanks, Angelo

25 to 30 thou is common for most of these old engines rough guide is the back of a broken hacksaw blade which when specially ground makes a great plug cleaning tool

instead of perfection some times we just have to accept practicality
