I have a 1963 40 hp with electric choke.<br />I cannot get the motor to start. If I spray starting fluid into the carb it will start and run 1 or 2 seconds and die. when I pulled the spark plugs the top plug was dry and clean it looked like it just come out of the box. The lower plug was dry but a little brown. The top cilender dont seem to be getting any gas. Several times I had gas running out of the throte of the carb when I was trying to start the motor. What should I try next
