If you carburetor float gets a hole in it, it will sink and no longer control the fuel level. A flooded carburetor results -- fuel runs into the manifold or outside onto the manifold.

Brass Float Repair

After removing the float from the carbutetor, the float may have some fuel in it. You need to get it out. If you can find the hole, hold the float so the hole is at the lowest point. If you do not see a hole, proceed to the next step. You may have to de-solder part of the float, to make a bigger hole.

CAUTION: THE NEXT FEW STEPS YOU ARE PLAYING WITH GASOLINE,
AND GASOLINE VAPORS. WORK OUTSIDE! NO OPEN FLAME! 
NO WORKING IN THE BASEMENT OR GARAGE WHERE THERE IS A 
PILOT LIGHT ON A FURNACE OR HOT WATER HEATER!

Get a large electric soldering iron, and heat the bottom of the float. This makes the gasoline inside the float boil, and pushes it out of the hole. Keep doing this until the float is empty.

Once the float is empty, find the hole, clean it, and resolder the hole. Check for air leaks in the float by holding it under water and very gently squeezing it, looking for air bubbles.

Once the float is resealed, put everything back together. You will need to reset the float level.
