Re: fuel line
If the engine hasn't run yet and its dripping fuel from the exhaust your engine is severly flooded. That's why it doesn't start.
Here are a few places to start:
1. Float is too high or not floating due to a crack and filling with fuel
2. You left the fuel petcock open and the float valve didn't shut correctly.
3. Carburetor main jet is not screwed in and allowing too much fuel into the engine. This is common. The jet wasn't tightend from the factory and fell out. It will be laying in the float bowl.
Start there and let us know what you find. We're assuming you are positive you have ignition and the choke is open.
