OK... my bad. The engine is a B&S Vanguard 993 cc V-Twin, 37 HP. Now that I see the oil related specs I am wondering if the "slope rating" is really about oil. From the literature:
- Oil cooler reduces oil temperature, improves lubrication and extends oil change intervals
- Dura-Bore cast iron cylinder sleeve assures long engine life and oil control
- Convenient oil drain locations for trouble-free maintenance
- Full-pressure lubrication with spin-on oil filter cleans oil and protects engine components to ensure maximum lubrication and long life
- Centrally located oil pump and pick up for faster priming allows for a higher angle of operation
- Pressure-regulated full flow oil filtration keeps oil clean longer, extends time between oil changes and improves bearing life
- Oil dipstick provides easy access to check oil levels
You thoughts now????????????????
