Float tabs come set flat to surrounding plate, bend up to decrease level and down to raise level. Raised level too much and you risk fuel overflow on sustained inclines and too low a level and you will lean out at high revs and damage valves/piston real quick. There is no set level to speak of, but better to err on the side of losing a bit of overflow. The overflow drains from the carby via a plastic hose from just above float bowl flange.

My bike smells like gas when turned on. it also takes time to stay on in the mornings when first starting it.ive also had turn off on me while riding.any help for my 2001 katana 600

Sounds like the floats in the carburettors are either sticking or their heights need to be adjusted.
They basically let the fuel into the carb bowls to a certain level & shut the fuel once they're full. Yours sound like they're letting in too much fuel.
It's a job for a bike mechanic & somebody who knows what they're doing.

1998 Katana 600 leaking fuel

Sometimes you can have success by tapping, fairly stoutly, on each float bowl.
The problem with anything else, is the carbs really need to be removed, and examined. It is the putting back on that is critical. The carbs need to be balanced. That is one reason to have a shop do it, if you're not familiar with the process.

Try the banging, and after inspect to be certain each carb is not flooding.

The bike was very hard to start and the petrol is pouring through the overflows

Float inside the bottom of carb is attached to a needle that shuts off fuel when the proper fuel height is reached inside the bowl. This tiny needle usually has a rubber tip that is pushed upwards by the pressure of the float. Trash on the seat of the valve, or improper float height are common culprits with fuel pouring out of overflows. you can clear trash of the valve seat by blowing into the fuel port on the side of the carb. You can adjust float height by bending the metal tab that pushes on the needle valve.

I went to install my carburetor,and when i hooked it up,and turned the gas on, gas was pouring out of the third carb right on the ground. how can i fix it?

The float is stuck in that carb, remove the carbs again remove the float bowl on that carb see if the float will move up and down easily including the needle valve if not strip it clean it replace all components adjust the float to the correct height(you will find that information in a workshop manual) refit the bowl again and carbs refill with fuel and see if it stiil overflows, if so you will need to strip the carb again and replace the needle valve.

Gas running from carb when the bike is running or not

Sounds like your float needle is not seating properly, or your float height is incorrect, or you have trash in the carb. It will need to be taken apart, cleaned, and the float height set. Look at the float needle for wear on the tip.

You need to get some new float needles, and have the carbs cleaned and the float heights set correctly.

KDX200 carb float set up. Hi I have gas coming

If you have gas coming out of the overflow tube, you need to make sure the float valve is shutting the gas off properly. The float height would have to be awfully high to cause gas to come out the overflow. You might be able to do it on the bike but it's a lot easier to do off the bike. Pull out the float valve and inspect the tip. Make sure it is smooth with no evident nicks or deep grooves.
