Overhead Valve (OHV) Technology	Improves combustion efficiency, reduces heat build-up, and lowers fuel consumption compared to side-valve designs.
Dura-Bore Cast Iron Cylinder Sleeve	Provides a hard-wearing cylinder surface that resists wear over thousands of hours of operation.
Dual Ball Bearings	Supports the crankshaft at both ends, reducing friction and extending engine life under sustained or heavy loads.
Magnetron Electronic Ignition with Auto Compression Release	Delivers a reliable spark every time while the automatic compression release makes the engine significantly easier to pull-start.
Maxi-Clean Dual-Element Air Filter	Automotive-style dual-element design captures more dirt and debris, protecting the engine in dusty outdoor conditions.
Float-Feed Carburettor with Mechanical Governor	Maintains a consistent fuel-air mix and keeps engine speed steady regardless of changes in load.
Super Lo-Tone Muffler	Reduces exhaust noise for quieter operation — less fatigue during extended use.
Duralube Splash Lubrication	Continuously coats internal engine components with oil during operation, minimising wear without the complexity of a pressurised system.
