Read through Operators Manual posted above. Adjust valves with engine cold, specs. are in manual above. Check air filter & pre-cleaner, spark plugs, fuel filter, oil & filter for replacement. I use B&S OEM parts with the exception of oil. I use Valvoline Full Synthetic 5W-30 engine oil 48oz. with filter change.
Run engine at full throttle before engaging PTO clutch & while mowing. I use 93 octane gas with Star Tron Fuel Treatment per instructions on bottle.
