110 John Deere carb leaking

The float setting might still be too high, or the float needle/seat is not sealing. That's about the only way for fuel to rise high enough to spill over the carburetor bowl. If you have a bad bowl gasket and you are operating on rough ground so that the fuel level is splashing around a bit, sometimes they will seep around that seam. But if the engine is sitting level, the fuel level should be below the seam where you have the leak. You might want to remove the carb and recheck the float needle and seat, and the integrity of the float. It's possible that the float is hanging up and not allowing it to "float" into it's needle sealed off position. If you turn the carb over so that the float falls against the float needle (the full "up" position), and you blow into the fuel inlet, it should not pass air if it is sealing properly.

I'd look for a flaw in the needle seat area, the float for a pin hole, floating rubbing on the pivot pin and hanging up, or debris under the seat area. It's an age-old problem that every one has to solve at one time or another.

Shake the float to feel if there is any fuel inside the float which could cause it to sink. Next would be to check the float for a pin hole by submerging it in a pan of hot water. If it is leaking, the air inside will expand and bubbles will rise out of the float at the point of the flaw. Solder repair the float if is leaking, or just buy a new one.

Once again, make sure that the float is swinging freely.

How the needle fits n holds to the float is a lil tricky, some have a lil hair spring while others fit into a slot but the needle cant be hanging up or binding just rising up n down nice n smooth as the float level rises with the gas.

If its a gasket or bore problem its hard to tell ya how to fix it sittin here.
