Was running as test out. After about 3 minutes, it started to smell as if burning (rubbing) metal. Then started to smoke around the starter area. I killed it as soon as I saw the smoke. Checked the oil before running an it was ok level. There is evidence of the started being convinced to turn over, (witness marks on the outside). Now it ast as if the starter has gone out. Which is fine! I noticed threre are several yellow 'oil' caps in various locations. I am not sure which one is what or the drains and filters that correspond to each other. As I pulled it back to the garage (that wasn't fun) the rear axle was making a click-clicking sound. Any ideas??? Thanks guys. Any help would be appreciated.
