So let's change spark plugs on our Husqvarna with the B&S model # 386777 1292G1 (23 hp) engine.
The tractor manual for the 2354GXLS says use a RC14YC gapped at .040
The sticker inside the hood says a RC12YC would be the correct temperature plug.
The Briggs & Stratton site confirms the engine should have a RC12YC gapped at .030
The web says the gap should be .032 to .038
I suspect it is not a critical requirement.
