Being as this is a 7000 rpm engine, it does not have a lot of port timing duration. But it has generous port area.

The spark plugs used in these is a NGK CM-6 Honda generator 10mm plug. It is a non-resistor plug.

You will notice that the new Husky 550, 555, 560, & 562 engines use a smaller spark plug which may be a trend of the future?.
