Spark plug mess

[phunter]

This is on my lawn tractor. What is the smartest way to change this plug. Air compress it, shop vac it. Kroil it. Hoping someone has been here before and can give some step by step.

PB or your penetrant of choice, let it soak, then brush and vacuum, then impact if it not move.

If it’s working I would not touch it personally. It’s not like a lawn mower burns up spark plugs.

I have never not gotten a plug out, they sometimes take the threads with them (aluminium head) or leave them behind (iron head) is the problem ….

Lots of rusty flavor there.
Definitely blow out or vacuum out any rust flakes. Use a pick to clean up close to the threads and then like he says, plenty of PB blaster, allow it to soak in, overnight, see if it breaks loose, if not repeat.
