Thanks for the reply Tbucket. I verified it was getting fuel by removing the poppet nozzles and visually ensuring they were spraying fuel while cranking. What is very strange here is that at around 2000rpm the engine is smooth and sounds good, but just to get it started requires 10 seconds or more of cranking while it is backfiring and once it does get going it idles like crap and will eventually die. I am beginning to think this is more than likely an ignition problem rather than a fuel problem. Given that everything is mechanically sound engine wise the only thing that I can see causing flames to shoot out of the intake is an ignition fault. Its just really hard to diagnose because like I say it smooths out and runs normal at 2000rpm.
