Try to start the engine with the choke on a few times. If no start, turn the choke off and hold the throttle open a bit while trying to start.
Holding the throttle open clears the flooding.
Try half choke and repeat.
Try that a few times and we'll move on to something else if it doesn't help.

Glad to have you here. Lots of good 2 stroke builders here. I'm sure they'll be able to help you.

I am trying to be condescending, but you should provide more information on what you've done to try and get the engine started. With the Internet, I have no idea of what your mechanical abilities are or your experience from past posts.

I assume it's a new kit. I assume that it was never running correctly. I assume that you put fresh fuel in the gas tank. I also assume that the engine/bike didn't get rained or snowed on while in storage. I assume you flushed the gas tank before installing the kit. I assume that you are running a fuel filter between the fuel tank and engine. I assume that the muffler isn't plugged with any manufacturing debris - quality control isn't a first priority with these manufactures.

Disconnect the kill switch. Try starting it. Check the ground wire solder connection on the magneto coil. I may look fine, but may have a cold solder joint. The spark maybe weak under compression and that's why it runs when you remove the muffler. Here's how to check the Ohms readings: http://www.grubeeinc.com/USA/Magneto Mystery.html

Check to make sure your carburetor jet isn't plugged and the float is set correctly. Also check to may sure the choke isn't stuck.

Good Luck,
