    16 hp motor compression stroke hang up
    I have a briggs and stratton 16 hp motor that will free spin with the spark plug out. With the spark plug in it comes to a complete stop on the compression stroke after a single revolution. By hand I can turn it past the compression stroke and when I hit the key it will spin until it reaches the compression stroke once again. Where would be a good place to start to track the problem.
