Well, didn't get a good seal around the spark plugs with the new water cover gasket installed and water came out of plug holes while running,<br /><br />ofcourse engine sputtered and choked, do I need to pour some alcohol into cylinder to get rid of the water, I figured the piston on down stroke pulls the water into crankcase?? thanks for your help. 1973 merc 200 20hp 2 stroke
