Get that car out on the road, tuning it in your garage is only going to get you so far. Those plugs are fine. There are shims under the cell, do a search on how they work, but since your pump was just setup, should be fine???? There is dry/wet fouling of plugs. My car has dry fouling, and I live with it. It has no effect on starting, for me. Wet fouling, I get that on my 2-stroke bike, at times. Usually when I let it idle too long after starting. Out they come, in go new ones until I clean wet ones.
Drive your car.
