I have a wee 3.5hp Mariner (circa 1980). After travelling at trolling speed for an hour or two the engine often floods; i.e. fuel drips quite quickly from around, what i assume is the carb and the only way to stop it is to shut off the fuel supply from the internal tank. is this an indication that the float needle is not seating ok? If so is it a major problem to remedy? Many many thanks <br />Scobius
