i have a 9.9 johnson outboard year 1977. It will start on one pull but it will not stay running. If i pull the choke in and out it will stay running but as sone as i stop playing with the choke the motor will kill.
Classic fuel supply problem it is best to check<br />fuel system from tank to carb.Clean and repair as required.Major problem is probably in carb but if system is dirty carb will continue to have problems.
