Neighbor said her x475 kind of back fired and shut off. I towed it up to my garage, it has sparked, I spray starting fluid into the carb and it will not fire. It does pop/back fire while turning over. Any help/suggestions are appreciated. Tha ks

Remove the valve covers and watch the valve action. Sounds like bent pushrod or valve issue. I've seen these engines gum up the intake valves on high octane gas.
