it will only fire when the high end is turned almost all the way in. about 1 1/2 to 2 turns out. the plug glows almost instantly when I hook it up to the ignitor. the fuel is definatley getting to the engine, seems too much to me but i'm stumped. If i flush the high end needle it doesn't even act like it wants to fire. just that blup blup sound as i pull the cord.
