briggs 17.5 hp cranks then stops

briggs 17.5 hp OHV on a yardman mower. When cold the engine will turn over for about a second then stop, I can turn the drive pulley by hand back and it will do it again. When I turn the pulley CW it will get to a point and stop, I forced it through the turn a couple of times and was able to start. Ran it for a while and it would continue to start. The next day when the engine was cold, same thing. The mower is about four years old and used on my lake place, it's not over used but maintained. Though I have never adjusted the valves, would this be a good starting point? Thanks
