Allright well heres the story... i've been running this engine for about 2 years, I rebuilt the carbs when I bought it. Never had any problems UNTIL..... the last time I was out it started right up and then everytime I would turn it off it became increasingly harder to start until I was being pulled back to the dock... It will turn over fine but no fire.. I tried starting it on the driveway yesterday and it fired a couple of times but than nothing and now it will only turn over... I took out the spark plugs today and they were black and slightly oily.. cylinder 4 had a considerable amount of oil dripping out of the plug hole (ounce or 2). Also I checked the fuel to carb 1 and it seemed fine... I would be thrilled to hear any suggestions.<br /><br />thanks in advance,<br />Andy
