Mine came with an NGK BPMR4A gaped at .35. Are plugs you show just preferred? Do you know what the ID/OD of the fuel line is? I was just going to use some Tygon but I can't find those numbers.

Thanks Fireman 123. My initial thought was that I preferred the NGK plugs. But after thinking about your recommendation I realized that there is no good reason that I can think of to have a resistor plug in a two cycle mower. The NGK has a much wider heat range than the CJ14, but so what. As long as the Champion CJ14 can handle the heat range that the Lawn-Boys operate than it is a good deal. I wonder why Lawn-Boy switched to the NGK resistor plugs for some of the later models?
