My 1979 115 HP Evenrude leaks a lot of gas/oil when parked. Doesn't matter if it's parked overnight or for a week. It had been hard to keep started at low speed like when loading on the trailer. Wasn't hard to start, but didn't idle well. Rebuilt the fuel pump and found there was no fuel filter in it and the diaphrams looked bad. The fuel pump doesn't leak and the engine now runs and idles better than ever before. The leak appears to be coming from the carb area and into the transom when the boat is stored with the motor tilted up. In reading how to rebuild the carbs, I read "disconnect the drain line at the rear of the air silencer base". I haven't taken the air silencer off yet because I haven't picked up a new gasket, but I'm wondering if this "drain line" might be a rubber tube, much like a fuel line tube, that like the fuel filter, had not been re-installed, thus causing this fuel leak. What does the "drain line" do and what does it connect to??
Thanks for any help or suggestions you may have.
