I have one of these too. I don't have any trouble starting it, except when I flood it. I am not sure if flood is the right term, but I know the crank case if full of fuel. I get mine going by taking out the glow plug, unconnect the fuel line and the return presure line. Then I turn the plane upside down and run turn the motor with my starter. Be carefull the fuel will spray all over. Then I put the glow plug back in and start the motor. It still may take a little bit to get it going. Then I re-attach the fuel and preasure line.
