• Design: The Courage series features a cool-running overhead valve (OHV) design and a tough cast-iron cylinder bore.
• Reduced vibration: These engines incorporate a dual-reciprocating balancer to minimize vibration, which leads to more comfortable operation.
• Quieter operation: An acoustically dampened air induction system helps reduce noise for quieter performance.
• Engine life: The typical lifespan is between 600 and 1,000 hours, depending on usage and maintenance. Consistent oil and air filter changes are critical for longevity. 

• Cracked blocks: A design flaw can cause engine bolts to back out and contact the flywheel, leading to a cracked engine block.
• Oil leaks: The engines are known to leak oil from the valve covers, which use a cork gasket. Some mechanics note that the fix is often temporary due to engine vibration. Oil leaks can also be caused by a clogged crankcase breather or worn piston rings.
• Carburetor problems: A variety of carburetor issues, including clogged jets, can cause performance problems like engine surging, stalling, or backfiring. A component called the after-idle solenoid is also prone to failure.
• Faulty starter: The starter on some single-cylinder models uses a design with a friction-based rubber disc, which can cause engagement problems, especially when wet.
• Starting issues: General starting problems can be traced to a weak battery, a faulty ignition switch, bad spark plugs, or a clogged carburetor. 

• Tune-up kits: A maintenance kit for Kohler Courage SV470–SV620 single-cylinder engines is available on Amazon. It typically includes an air filter with a pre-cleaner, an oil filter, a fuel filter, and a spark plug.
• Carburetors: Replacement carburetors for the SV470–SV620 series can be found on sites like the Hipa Store and eBay.
• Long blocks: For significant engine failures, a “long block” replacement is an option. Engine4Less.com sells a long block that services all single-cylinder SV470-SV620 engines and includes the electrical system.
