I just bought is motor, took it out and started first pull. I put in forward ran it for 15 min then stopped and fished for 30 min. Restarted shifted in forward work fine then neutral then reverse worked fine then forward ran for 5 min turned off. When I restarted it stuck in reverse and after working with it got in forward, while taking it back to the dock at slow idle it staled and would not let me pull start it unless turned the tiller handle all the way to the left then the pull string would release and after a couple times it started . What could this be , Thanks
