Obtained this Engine from Original Owner. He ran it on a Dune Buggy. It has an older square Carbureator. When I spin the prop, I feel pits in the Bearing. Is this normal? I also am missing what appear's to be a Sleeve Plug in the Rear Crankcase area, right above the back cover. Might it be a Sleeve lock plug? Also am missing a lock screw to hold in the Carbureator, along with Two long muffler Screws, which attach muffler to Engine. Any help would be appreciated.
Thanks!
