I store my sleds inside and once a month start them up and let them run for 10 minutes. Saturday I started up the 550 fan and it ran for about 1 minute and then stalled. I proceed to try starting it again and it would only start a few times with the choke on half way and run for 5 seconds. It will fire with starter fluid but not run. I took the spark plugs out and poured gas into the cylinders and again would fire but not start. It's seems obvious that it's not getting gas. Anyone else ever have this problem. I have a game plan but would like to hear from others first.
