I have a 1995 Johnson 50hp mod

I have a 1995 Johnson 50hp model J5BELEOD that I am concerned may be running to lean. I pulled the plugs out after about an hour of use on new champion QL78YC plugs. The top plug had a yellowish color to it with no signs of blackness or oil on it. The bottom plug was pretty much clean with a little bit of black around the middle. Maybe I'm just used to older 2 strokes that always turned the plug black almost right away. How would I go about adjusting these carbs to run a little richer?

"The oil injection has been disconnected on this motor so I mix it 50:1. I'm not sure that it is to lean, just figured the plugs would get dirty a little quicker on a 2 stroke than they are. It was running at close to WOT for most of the hour I had it out so maybe thats why they didn't "foul" at all. I will buy a manual hopefully this week if the marine store up the road has one in stock."
