Spark plug question.

[*WEAVER*]

I have a 1990 mercury 90 horse 2 stroke. I've pulled the plugs off of this a few times, and they have what appears to be black oil on them pretty heavy. Is this normal for a 2 stroke, or am I possibly running it too rich? Thanks

Re: Spark plug question.

It sound like your running to much oil,but id rather run too much than not enough! As long as its not fowling out on you i would'nt worry to much.
