Use some "Start Ya Ba...." to see if it runs, then you can rule out ignition timing faults. A 5second squirt in behind each butterfly should do it and open the throttle a fraction to give some air.
If it runs, then it may actualy continue to run on fuel once started.
If not repeat the above. If it runs and stops again then there must be a fueling issue. If your getting the occasional cough then there's obviously a small amount or too much fuel. Check to see if the plugs are wet.
If they are, put them in the oven for an hour on 100c to get them dry.
