1981 2hp evinrude.. runs with choke on for couple minutes. Then i have to keep feathering the choke to make it run reguargdless of the throttle setting. It wont stay running in any one choke position. Im thinking maybe the float isnt allowing enough gas in the bowl. Does that make sense to anyone? But if you guys have any other ideas or better suggestions please let me know. I was just gonna take it to a shop and say FIX IT.... but nobody will touch it for another 3 weeks... Please help....
