YT175 wont staaaart

[angryyoung]

It will start and run for about 10 seconds with the choke on and if i give it any gas it stalls out, it wont start at all when the choke is off. the spark is weak apparently (orange purpleyblue spark). what is my problem? I rode it last week with no problems. The machine is a yt175

dirty carb it is not sucking gas on its own.

ya think so? i just cleaned it out less than a month ago. what could be some other problems?

try starting it with the gas cap off----
or ignition timing from a torn crank key.
