Check your reed valves, they must be fully closed to prime. If not you will have to change them. (Had the same problem with my 3W50)

RE: 3W STARTING PROBLEM
I'm going to say try this one more time. OPEN YOUR LOW NEEDLE ONE TURN. You can reset it after the motor is known to start correctly. If you know the choke plate is closing all the way then this is your problem. The reason for the hard starting is because it has sat for a year. You have oil in the carb passages that has thickened causing the low needle to act as if it is too lean. If all else fails then pour raw gas into the cylinder through the plug hole a few times and it will come to life after a few tries.
I just got done going through this with two DA150's and they both would not start without raw priiming. Both had set for over 6 months without running. Hopefully the low needle fix will do it for ya.
