The float should be free on the hinge pin. Clean the pin and be sure it is not bent. Is the float mounted upside down? Check to be sure the float still floats > If a pin hole , crack or corroded solder seal lets fuel into the float then the bowl will overfill and leak. The float needle is in place isn't it? Please rate my answer. Thanks.

1974 kawasaki 900Z1 carburater bowl over flow spilling gas

The float is either not closing fully due to a bit of trash preventing it from fully sealing or the float is stuck open. Another possibility is that the float has a pinhole in it and no longer floats. Remove the float when you clean the carb then check it. It should be light as a feather and have nothing but air inside it. If the float is bad, it looks like Babbitt's has them. Please rate my answer. Thanks.

Gas flows out of overflow tube on the bottom of the carb. Re: KLR 250 Kawasaki year 2002

sounds like your carb float has stuck and letting the fuel overflow, remove float bowl or carb clean check if the float has a leak shake it and you will hear fuel inside , refit and check

I need to reset the float levels in my carbys to stop the overflow on my 1974 Z1A Kawasaki

You describe a problem with either the float or the float-needle and seat. If the needle is not seating then the gas flows past it. If the float has a pin-hole leak, then it will fill with gas and sink.
On some bikes you can remove the carb bowl without removing the carbs. If so, slide the hinge pin holding the float to one side and remove. The float will drop straight down. Catch the needle since it is now loose. Unscrew the needle seat with a socket.
Clean all metal parts in carburator not get carb cleaner on any rubber part. Shake the float and listen for gas inside or see if it floats in water.
Test the needle seal in the seat by blowing gently thru seat. Needle must seat completly with very little pressure holding the needle in the seat.
Re-assemble with new bowl gasket if damaged. A carb rebuild kit ($35) might be available for 1973 carb and contains all new parts instead of cleaning. Kit might even contain new float and float adjust guide.
Avoid adjusting float level if re-using the old float. If using new float, temporarily install old and measure distance to carb body. Install new and match this measuremnt. Bend tang to adjust.

Good luck,
