I have a zdz 50ng..and from the get go.its a bear to get gas..but I do have method that works for me.
I turn on plane, radio, but ignition off. Then I open up throttle full, close chock full and crank the heck for about 15 to 20 cranks
I then put radio to idle, take off choke, turn on ignition, and boom...it starts in first or 2nd toss.
My take is a well back in fuselage..and I think it just takes a few cranks to get up the line.
Give it a try.
