in the past while working on motor, i had the dark oil floating on top.now though it looks to be white like maybe its water in my mix. i also took the plugs out and when i shake them really hard i can get what looks to be water drops. do i have water in my gas? i just got it yesterday. or is my motor pulling the water from the barrel in to my cylinders. it seems to be running ok. its also pushing water out ok.
