I have a 99 mercury 40 horse oil injected engine. I noticed gas in the water after i ran it the last couple of times. When i pulled off the cover is seen gas pumping out of a threaded hole in the middle carb. All three carbs have the same threaded hole with no screw in them, but the middle one is the only one that pumps gas out. This hole is just left and slightly above what i think is the idle screw. Has anyone had this problem.
