You can get the float valve assembly for your Kawasaki KE 100 on Ebay.
Isolate it from the water supply then replace the defective valve
What if your float is not floating? Food for thought... If your float has gone bad then it wil not give enough force to close the Float Valve. Get a new float. If this does not fix it then the float valve you got is defective.
It very well could be, or a problem with the float. Remove the bowl off the carburetor, remove float, needle valve, and seat. Clean all parts good with carburetor cleaner. Float the float in some fuel to make sure it floats (when should not that any fuel inside of it). Put needle valve, seat, and float back on and open fuel valve a small amount, lift float up to see if it will shut fuel off, if it does reinstall bowl. If not you may have to replace the needle and seat.

I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high. I would replace the needle valve and seat and check float level.I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high.

your float and or needle valve is allowing gas to flow through carb into engine.These should be replaced.
