Default RE: ys 140 sport problem

well it finally started: but the throttle had to at wide open to do it. i thought i'd try that as a last ditch try. i ran it at idle for 20 or so seconds, ran it up to full throttle slowly and set the high speed needle. rpm of 8500 + or- 100 rpm. than tried to set low end every time the engine would get around 28-2900 rpm it will shut itself off just like you turned off a switch. i also noticed that if the glow plug driver was removed at or around the same rpm the engine would shut off. anybody have any ideas? i guess that in the future that inorder to start this engine to do so at a near full throttle position. i do not like to do that.
the low speed needle is set at 1-1/2 turns out
