So I have this bike and the issue with it seems to be gas delivery. Now I took apart the carb and cleaned it meticulouslywith a variety of different width wires and about 3 cans of carb cleaner. I checked the lines, all good, gas flows fast if disconnected from the carb (it has a manual petcock). Inside the carb the floater is a metal floater, no rust, some old residue from gas but all that could be cleaned off has been, however one side of the float is bent a little bit inwards. Would that effect float and cause it to not let gas flow through the carb? It starts every time when I put some gas in the air intake side of the carb and start it up at the same tie and will run until the gas is gone from the intake side. No gas seems to flow through the fuel line (clear tubing so I can see). All jets and passageways are clear in the carb. I literally spent 3 hours cleaning the jets alone until they were spotless, they had very hard gas clogging them and the atomiser, but as I said I meticulously cleaned the carb and the only thing I noticed was the floater was a little bent.

Since you spent as much time cleaning it as you said, I assume the inlet to the float needle was also done. If this inlet is clean, and the float and needle are working properly before installing the float bowl, then the float needs to be adjusted, or it's the wrong one for the carb. Does it seem to large for the bowl? Do you think it maybe it is touching the bottom, or some other part of the bowl, keeping it from dropping, and the neddle from opening?
Normally when this type of float fails, it's because of a crack or split seam, which allows it to fill and sink, thus flooding the engine. I've had old tractors that would occasionally have the float stick shut, a couple of taps on the bowl, with a wrench handle would usually get it to restart and back to the barn.....but I knew it needed a good cleaning, and maybe a carb kit.

my thoughts exactly hillbilly,,,either the float needle is stuck or there is something wrong with the float itself,,,,does the float bowl have a web down the middle and the float is touching it cause it's bent?

No, it's not obstructed at all.
