Have a strange problem.
I have a 1984 mercruiser 140 3.0L. Mercarb 2 bbl Carb. Manual fuel pump. I started the boat and ran it for a bit on the water muffs and the boat runs good. I noticed that if I let the boat sit for a while in the garage, when I go out to start it the next time, it takes a little bit for the fuel to get up to the carb. SO it seems like the fuel is returning to the tank or something. That has been happening since I bought it.
Now, I just bought a new boat cover. I put the boat cover on the boat, and left it in the garage for a few weeks. I went out the other day and removed the boat cover to access the engine. As soon as I removed the boat cover and my nose was punched with the smell of gas. I lifed up the fuel door cover to access the tank, and there are no leaks around the tank. I checked all the lines from the tank to the carb and all have clamps on them are no cracks. Is that gas smell coming from the throat of the carb as the fuel bowl empties, or what else could it be.
