Any one have a site that shows the engine break down. I need to know if the bolt on the right side of the engine on the cylinder head, There is 2 of them. It looks like they hold the head on. I need to know if they are the same lenght? I just purchased a used Rancher and one of those bolts was loose and it looks like the head has been off. I went to tighten it and it just spun. so i removed it and it was about 2 and half inches long. But the one next to it was like 5 inches.
