Hey Paul are you flipping this engine fast? The prop has to go by the sensor with a good bit of speed. It has to sense a bit of rpm to fire , a safety feature.

Cold I flip 7 times choke on full throttle, then ing at idle first flip it starts. Most people dont belive it will start that easy.

Hot I flip it 4 times with the throttle open, then idle and ing on first flip.

I have not found the difference in the neddle setting to be to important for the ease starting. Also I never try to start with the choke on untill it fires one time. This has always caused me flooding problems on all my gas engines.

If this dosent help send it to me and let me try it.
