Has anyone ever locked up there motor or heard of one locking up. Because i picked up my dad and had to shut off engine. When i went to start it up it turned over for like 2 rotations and stoped . I thought it was the starter and replaced it. But nothing try to jump off nothing. Then i noticed my clutch cable is cracked and leaking fluid(finally found that leak 1 of 5) and thought maybe that was the prob.
