90 HP Johnson Fuel leak

[pochejp]

Leaking fuel from under lower carb from some kind of little port coming out of the block. Motor runs fine at all RPM's but fuel is leaking all over the motor mounts. It appears to be a hose connection but I can't find any loose hoses or fittings. Any ideas?<br /><br />Thanks,<br /><br />Jason Poche

Jason,<br /><br />There are crankcase vents that should have hoses going from the block (near the back of the engine) to ports behind the carbs. These ports vent unburned fuel from the crankcase and return it to the intake just in front of the reed block.<br /><br />Take a look at the back of the block, there may be some electronics over it. Look for small vacuum hoses running toward the front of the engine-there will be two on each side.<br /><br />You will have to remove the carbs. to reconnect them.
