The air filter that hangs off the carburetor should be coated with air filter oil. If it's dirty, wash it out real good with warm soapy water. Let it completely dry, reoil it with air filter oil and put it back on. Make sure you prime your motor before trying to start it. The easiest way is to take the fuel line off the exhaust and blow in it. You will see the fuel move up the fuel line. When it reaches the carburetor and the air bubbles go out of the line, stop blowing and put the line back onto the exhaust. Now put your glow starter on and try to start it. Also, when it does start, it's OK to give it a little throttle to keep it running. It might idle a lot better once it warms up. I normally start mine with the wheels off the ground, that makes it easier to keep it running until it warms up.

If you are getting unburnt fuel spitting out of the exhaust header where it meets the motor, you may need a new gasket. Or, try repositioning it to get a better fit. If you are getting fuel spitting out of the plastic coupler that joins your muffer with your header, you may have a break in it or you may need to put new zip ties on it and tighten it up.

Congrats on your new toy and welcome to the Savage club.
