Plowing yesterday, running great, suddenly dies. After cranking over for probably 45 seconds, it starts back up, idles perfect, but as soon as I give it the gas it dies. Replaced ignition box last winter. Seems like a fuel delivery issue. Any thoughts?

 

Check the needle in the diaphragm slide. I bet the e clip came off or the needle broke at the top. Just pull the air box and intake tube, lift the slide manually from the back of the carb and see if the needle raises with it, or doesnt move and stays in the emulsion tube.
