Fuel is leaking from line that connects to carburetor. The line looks like it's an overflow/drain line, but also looks like it may connect back to carb (I see a nipple that fuel bubbles from when I open throttle), but the ID of the fuel line is too small to fit over the nipple. It might require another connector piece. I'm looking for a schematic to see if an how the fuel line is connected.

Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Check the float as they can go bad and fill with gas such that they no longer float. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. The idle speed will probably different so adjust the idle screw to get back to where it was. This process should get you back on the road.
Please rate this solution. Thanks!

Turn the petcock valve off and the flow should stop. If the fuel line is long enough, cut the broken line just above the break then re-attach to the nipple.

sounds like you need a new clutch. but first make sure that your clutch cable is'nt too tight. it should have a little bit of freeplay when you pull the lever.

that would be either the float set to high or the needle and seat is missing an o-ring while you had it apart. Should look at getting a carb kit there only approx. 23 bucks and it would save you a lot of grief in the long run.
