I only pulled a couple on each side they were clean and no wear at all it runs great just hard to start when its cold
You should pull them all. Chances are you have a few that are dirty. That makes them hard to fire when cold but can get better as it warms up.
Make sure the gaps are correct also, this can make a big difference on cold starts.
