I pulled the thing 20 times it wont go. I used some starter fluid (i know i'm not supposed to) it fired up first pull. Stays running, runs good when I can get it started. Except when I open it up full throttle it will stall. Then when I turn the motor off for more then 5mins or so, it will not start without the fluid.. I am somewhat new to outboards, but I know a little. Any help would great
