Spark Plug Status?

[l008com]

Yes I am aware this plug is unusually wet, which makes sense as the mower wouldn't start. This is the machine that turned out to be overfilled with oil.

But I'm only making this post to ask, what is the condition of this plug itself, not the motor overall. Besides behind wet, this plug looks old but barely used. Like someone replaced the plug years ago to try to get it running, but it still wouldn't run so it sat around for a few years?

I know plugs are cheap but I hate replacing something that doesn't need to be replaced, does this look good to keep using?

It may look good, but could be compromised. At the $$$ of plugs I would be replacing it. Dollar wise many times mean penny stupid.

Well it either fires or it doesn't even if it looks good , if you ground the end and spin the machine you should see a spark , if no spark it may be a coil problem. The plug does look in new condition but it would look like that if there's no fire also.

The way i look at spark plugs... "it could be a $3 fix"

That plug must of come off of an airplane. Because at my shop it would be taking its last flight across the shop into the trash can.

How to test a boat spark plug

Drive to the middle of the lake
Remove spark plugs
Carefully place them on the water

If they float they are good
If they sink they are bad
