I'm with Liquid_TR never have I heard of the low needle this far out-its a wonder it would even run!! I had a similiar prob. with mine in the beggining and that was that I had a brain fart and had my throttle end point at a setting that was keeping the butterfly from closing all the way-lacked 1/64" or so and that little bit made a HUGE difference! Now, my DL idles 1700 all day long or lower if I wanted it to.
