305 tpi question

I was working on getting all my a/c out of the car tonight so i can replace everything with new stuff, an i decided to look at all my spark plugs, #3 had some raw fuel on it? what would cause that, i already eliminated the cold start injector for fuel related problems, are my heads going now ? or is it something like a leacky injector, the car runs very well! and has tuns of power, so im wondering why spark plug #3 would have been wet?

Easiest diagnosis is a bad #3 injector. Do a resistance check on each injector using an ohm meter. You should see between 13-16 ohms when hot. Anything less and its probably bad.
