Different problem. For those of you who responded to my chain issue, thank you, I think I have that fixed (I did move the rubber spacers inside and also changed the tension on the chain).
On to the issue. I'm trying to start my bike for the first time. 48cc Grubee Skyhawk 2 stroke. The first time I put gas in the tank after installing everything, the result was gas pouring out the carburetor from the overflow tube as well as the air filter. I know nothing about carburetors aside from what I've searched for and read on these forums the past couple days, but I was fairly confident gas should not be flowing from it, so I took the cover off, found what serves as a valve for the gas to enter the bowl, and found I could adjust the flow by bending a piece of metal inside.
I've had that cover on and off a hundred times in the last two days fiddling with that piece of metal, and the results of my efforts are these:
A) The bike doesn't start at all. I presume this means it is getting no gas. To test, I put a few drops of gas under the spark plug and try again - it fires up, and then dies. So, I open the carb again and bend the thing out some.
B) The bike starts, runs a few seconds (the longest it ran was about 20 seconds, most attempts have been more like 4-5 seconds), then dies, and immediately after it dies gas begins pouring out the overflow tube and the air filter again, and will not start again (flooded, I imagine). So, I open the carb again and bend the thing back in some, and we go back to scenario A.
I've been assuming that there must be a happy medium between the two and that I need only find the right tension on that piece of metal, but I've been between scenario A and B a hundred times now, so maybe I'm missing something. Here are some pictures to illustrate what's going on.

Any ideas?
