Today we're going to replace the spark plug on a Honda HRX426 Lawn mower. Firstly, if the engine has just been running, don't touch the muffler and the spark plug, which will still be very hot. When satisfied, pull off the spark plug cap and remove the spark plug using a 21mm plug spanner. Inspect the spark plug, and replace if there are lots of deposits or if the insulator is cracked or broken. Check that the sealing washer is in good condition, then screw the spark plug by hand until finger tight. Then using the spanner, give an additional ½ turn for a new spark plug. Refit the spark plug cap. That's how you replace the spark plug on a Honda HRX426 Lawn mower.
