The saga continues...had the merc on the lake yesterday and after running it for about 20min noticed about a pint of gas in the bottom of the boat. We loaded it up and pulled the covers and we noticed a drip from the top carb (near the front) when I pumped the bubble on the gas tank, when I tipped the engine up. When we were running the motor I had to continually pump the bubble as the engine would start to stall from lack of fuel. Today I tipped the motor up, opened the throttle (motor not running LOL) and pumped the bubble, saw a steady stream of gas running out of the front of the top carb. These carbs were rebuilt earlier this summer by a mechanic. My initial thought is the front plug is loose or missing. Can't really see it without doing some major tear down. Thoughts? Any help would be appreciated, needless to say I won't run the motor until we fix the leak. Might be a large mushroom cloud on the lake.
