Answer
Remove the connector on the end of the plug. If the plug looks to be rusty, give it a shot of WD-40 & let it sit for about 1/2 hour. It would be good to already have a spark plug wrench and a small wire/brass brush.

The brush with the wd-40 can clean up the plug if necessary. Then take your plug wrench on a ratchet & give it one quick turn counter clockwise. If you feel it loosen...continue in that direction. If you don't feel it break loose, turn it once quickly clockwise, then repeat in counter direction. Back & forth until you feel it loosen.

You do not want to force it hard in either direction past the once quick motion. Doing so can cause the ceramic core to fracture & break & then you really have a big mess on your hands.

In instances like this...brute force is not your friend. Once quick...one way then the other until you can easily unscrew it counter clockwise. I cannot stress this enough.

Answer
0-make sure mower is off and the fuel tap switch is off.

1-gently pull back the little L shaped black rubber boot from the top of the plug. if no boot, then skip step

2-get a clean rag and the new spark plug ready ontop of the mower.(if you need to take the plug along with you to buy the new one, follow below and stuff the rag in the hole while your gone).

3-.make sure the area is completely clean with the rag before unscrewing

4-get a shifting wrench or if it's sunk down, then a sparkplug sized socket(there are 2 sizes) and wrench and turn anticlockwise, if it's stuck then apply a steady even build up of pressure until it comes loose.

5-put in the new plug and turn it till a little hard to turn then follow the directions on the plug box to see how far to turn the plug after that, 1/4 1/8 or 1/16th rotation. replace wire/cap/rubber L boot

6-turn on fuel tap again

7- give it a whirl, If nothing then, check the connection to the top of the plug and to the coil.
