this is a dumb ? but are you giving it any gas when you are trying to start it ? if you are you might be flooding it just a little, try this just turn the ket on but not all the way just to energize the system for about 2 seconds then turn the key and see if it will start with out giving any gas, then you can give a little gas. just a thought.
