    I have a 1974 hayter 21 (the one on the left of the picture). Does anyone know what spark plug it should have? Can’t seem to find a manual anywhere for it.

    Hi Charlie.

    It is a 5hp Briggs and Stratton Engine – Does that help or do you need more info?

    Thank you for the suggestions, I have ordered some. The mower was running very rough and having taken the carb to bits and cleaned up the ignition, re-setting the gaps, it still ran rough. Changed the plug for one from another mower and it runs better than ever. Just want to make sure I’m using the right plug.
