Most likely you are flooded or over-primed. Dry the engine out well. Then with the glow battery removed and the carb open cover the carb intake with your thumb and (by hand) turn the engine over until fuel in the line just reaches the carb inlet. Then give the engine 2 more complete turns. Set carb/throttle to just above min idle setting (stick down but trim high usually). Attach glow battery and apply starter for a few seconds. Should now be running. If not, try starter again.
