TECUMSEH HS50 5 HP HORIZONTAL SHAFT ENGINE USED OFF OF SNAPPER I522- ELECTRIC STARTER. Good engine, runs with gas sprayed into carburetor-may need tune up/carb work- starter is good. 2 shafts- 2 1/4″ with 3/4″ diameter- Keyed only; other shaft 13/16″ long with 1/2″ diameter- tapped and keyed. Would consider pulling starter off to sell separately for a lower price. NO OIL, NO OIL.
