Spark plug stories

Probably running too rich.

However, IMO if you are not experiencing any operation issues, "Don't fix it if it ain't broke."
 
I had an issue with some water and a trash in my tanks and she was popping and sputtering. Replace the water separator that helped for a while but it kept happening so I replaced the 30 year-old tanks. Ran great for a little bit but then started popping and sputtering again. Today I replaced the plugs but it’s still doing it so I’m thinking coils now. Any ideas?
 
Carbs or EFI? I also voted with running rich. If Carbs, probably need to adjust those.
 
Carbs. Just talked to a mechanic friend, he agees with y’all.
