We pulled up compression stroke on number one cylinder and checked rotor to see if it jumped tine. Checked vaporizer and regulator. We even pored gas strait in and tried starting. Pulled plugs and were not even wet or smell of gas. Compression and suction at carb. feel good. Fuel is not getting into cylinders. Starting fluid , it doesn't even act like it wants to fire. All plugs stay sparking when spinning engine over.
