1994 J150 leaks fuel on starboard side under carbs

[jwellcraft]

Just completed a full rebuild on a 1994 Johnson 150 Ocean runner 60* looper and after I started and ran it for a few minutes on the hose there is fuel draining somewhere under the carbs on the starboard side. I think this is quite common on these and it did leak before the rebuild but I took apart all the carbs and cleaned, inspected and assembled everthing back and it still has this leak on that side. Any suggestions? It isn't a constant flow just a drip and once it's left over night there is fuel drain stain down the exhaust housing under the cowling.

The most common place they leak is around that BB in the side. We always put some epoxy around them while going thru the cleaning process. Another area to look at is the bowls themselves. Sometimes they warp.

Thanks Dhadley, the ball bearings on the side already have been epoxied so it might be the bowl and it seems it's only one of them. I know when I tilt the motor up and put the manual choke lever to it's choke position and pump the ball fuel runs out of one caburetor bore, it this normal because I think that's the carburetor where the fuel is dripping from.
