I have a mid 80's Mariner 20 on a pontoon that starts fine but only idles and runs with the choke on. As soon as you put the choke off it dies. As soon as you give it power in gear it dies with the choke on or off. I can get it to move just above idle speed in gear with the choke on and thats it, will die when I advance the throttle. I put new gas in it and changed the spark plug....no difference. Sounds like a fuel problem. Any suggestions??????:confused:
