Default RE: DL-50 engine

JoeAirPort.......Need a little help. I purchased a new DL55 recently, I have it mounted in my airframe, and it's ready to go. Fueled it with 97% octane with a 32:1 mix of Penzoil Air Cooled. I haven't touched the factory setting for High & Low speed, however a friend of my dialed the idle speed needle all the way out to where it isn't touching the the idle arm. I've tried to get the engine started by slowly turning in the idle speed needle about 1/4 turn at a time. It seems when the idle speed needle is about 2-1/2 turns in the engine will fire but not run. A little more turn in and it wants to run for about 1-2 seconds, then quits and it takes about 4-6 flips of the prop to get it to fire. I've got good spark with a 4.8v 1800 mHa NiMH fully charged battery. I have the throttle linkage set to where the throttle on the Tx is fully retarded and there is no tension on the carb. throttle arm. I can move the throttle arm toward to open position by either turning in the idle screw or opening the throttle on the Tx. When I get the engine to momentarily run I've tried advancing the throttle slightly, only to kill the engine, then it seems like it floods, not wanting to start at all. I'm baffled, I've heard everyone say it's a breeze to get these baby's started. Any suggestions? Mike
ps: I have the stock plug in and the gap set at .020. I'm trying to locate a NGKCM-6 plug.
