what i have: 1980 200johnson 6cylinder<br />problem i'm having: every time i turn off the engine and start it up again, i have to let it run, sometimes need to choke, for a minute or two before i can move or will cut off. happnes every time i move from one fishing spot to another. replaced fuel line, filter, bulb... doesn't seem like a gas problem. don't know what else it could be!?!
