Hi Jack - We need more information, like what kind of bike it is and how old it is. If you have no mechanical knowledge whatsoever, it might be wise to take it to a shop to have it looked at.

The basics are this - Your bike needs 4 things to start - Air, Fuel, Spark and Compression. First check for spark, then fuel and go from there.

It's probably something really simple ... maybe your petcock is switched off or you have a kinked fuel line?

How do you switch the petcock? how do you troubleshoot "kinked fuel line"?

Did you get an owner's manual with your new bike?

It -should- have a description of the petcock (or fuel valve.) Hopefully it's not in Chinese

Once you read about the petcock, and you are sure it's on, you can follow the fuel line from it to the carburettor, and make sure it's not pinched or kinked.

Is there gas in the fuel tank?

a stall during idle and a failure to start after that could be the result of no fuel in the gas tank.

petcock? that is the thing that you turn this knob to set on ON/Reserve/OFF? Its turned on "ON"

I wonder if there is some type of vacume problem?

and yes, there is gas in the gas tank.

Switch to Reserve and see if that helps. The most likely culprit then is that the fuel level in the tank is to low for the 'On' setting pickup tube. The 'reserve' tube is shorter and allows you to use the fuel that's in the bottom of the tank.

If it's got a kick starter too, try that.
