Help with 1978 Johnson 85 hp!!

[SwampRunner]

I've got a 1978 Johnson 85 hp outboard thats kicking my a**! I apologize if this has been discussed already but I couldn't find it. I'm getting no spark in one of the 4 cylinders. I've changed the power pack, coil pack, spark plug and wires, still nothing. Any ideas?
