Jd stx38 kohler 12.5. how do I release the hood at the front to change the spark plug? Also what spark plug does it take? Thanks, ron

Hi,
There are two brackets and springs. A short piece of rope doubled into a loop attached to the hook of the springs and a pull to unlatch, swing the hood open and up out of the hookd in the brackets. See the picture and there should be two each of numbers 4 and 6.
Peace,
Clarke
