you need the flue mix right,when you pull the cord to start for the first time, have the choke on" when the choke fires, turn the choke off, then pull it again to start, sounds like your flooding it, because you did not turn the choke on or off at the right time, take out the sparkplug and clean it with sand paper.start it with the choke on, pull it till the choke fires, will will feel the choke fireing, then turn off the choke and then try it.
