I would first make sure that the drain tube stop screw is in place and tight.
It's at the very end of the black drain tube shown in your photo. Look for a flat head screw on the very tip.
If that's not it, I would then check all the fuel lines and the fittings. They get old and develop small cracks.
That's what I'd check first

That looks like a lot more fuel than is in your carb. bowl there so I would suspect that your vacuum petcock is not stopping the gravity flow of fuel to your carb. and your float needle valve/seat is allowing it to leak and overflow the bowl. If the fuel line was indeed shut off, this could not happen. Bill PS I would not smoke in there for a while if I were you.

So being that it would not leak if petcock was closed;How will I know if fuel petcock needs to be changed? Also does it appear that my fuel filter is installed correctly I never see fuel inside of it.

It is possible that your drain hose had filled up over time...a little here... a little there...and suddenly developed a crack or leak and dumped it out so I would check that as humanshield suggested but...that still looks like more fuel on the floor than that hose could hold...maybe not...but I am still thinking it has to be the petcock.

I changed to my spare carb and filled up with fuel. There were no sign of leakage. However my starter bolt is still stuck inside case. My c clamp mid worked yesterday but it won't hold the starter in place to day to turn over engine correctly.
I will have to drill out the bolt

(Like dipping a straw into a glass of water and then holding your finger over the end...the water can't come out when you take the straw out of the water.) I hope I am clear in trying to explain this. Bill

So remove the fuel line to the carb and see if it's leaking? Because it should only come out under air pressure from the crank or electric start?

First I cant stress enough about the dangers of gasoline fumes. Especially in a enclosed area. An arc from a light switch, plugging in your phone charger, ect. This time of the year when static electricity is more prevalent, you are lucky you did not blow anything up. You are playing Russian roulette with your life, family members living there and others that are living in the same building.
Now for your fuel leak problem. Remove your vacuum line and fuel line and place the two hoses in a bottle and let them sit for a while. If the bottle has more fuel in it(other then the residual fuel that drained out) then the petcock is faulty. If you are still have leaking fuel other than what was collect in the bottle then you have a faulty fuel lines and EVERY inch of line should be replaced.

Your first line of defense against a fuel leak like that out of the carb is your petcock. It uses the vacuum from the engine to open the diaphram inside of it to let fuel flow to the carb when the engine is running and should cut off the fuel flow when the engine stops when working correctly. They commonly fail which is why many of us replace them with a simple on/off fuel valve. Of course then it's up to you to remember to shut it off manually... The second line of defense against fuel leaking out of the carb/overflowing is the float needle inside the float bowl. If your float isn't adjusted correctly, or if the needle isn't sealing correctly it will allow fuel past it and overflow the carb bowl. I'm guilty of not shutting off my manual fuel valve for weeks at a time, but the 2nd line of defense- the float and seat in my carb- adjusted properly keeps any fuel from leaking! Having a float/needle that isn't working correctly can often also flood the engine and be a culprit in very hard starting....

Locate where the fuel leak is coming from for a start. Then look upstream instead of just guessing.
