My Homelite Super XL Automatic, currently not running. Circa 1975. The Homelite (Walbro) SDC carburetor has "8 74" stamped on it, and the date wheel on the crankcase suggests it was made in June of 1975. It has a 16" hard nose gas welded bar and full chisel Carlton chain. The cylinder was cracked, and I replaced it with a good used one along with new bearings and seals.
