I have a snapper riding lawn mower that i think isnt too old. maybe 2000. I am going to try and post a picture with this post. But anyways, I try and start it and its like the gear that turns the main flywheel just keeps spinning. Well i bought a whole new assembly for it and it has worked like a charm for about 2 weeks but now its doing the same thing again. I can't figure it out at all. It is only an electric start. Please help......
