About This Kohler Small Engine
This Command series engine uses an overhead valve design with an aluminum block and cast iron cylinder liner, a full pressurized lubrication system, and a vertical PTO shaft built for riding mowers and garden tractors. Kohler built this same basic 426cc single cylinder platform across several closely related model designations, including the CV14, CV15, and CV460 series, which share many internal components even though displacement and horsepower rating differ slightly between them, so confirming the exact model and specification number stamped on the blower housing helps ensure an ignition module or carburetor is built for this specific engine rather than a similar sibling. The electric starter runs on a 12 volt system, and the recommended spark plug gap is 0.040 inches on this engine family. This engine idles in a range of roughly 1650 to 3350 RPM and uses a dry air cleaner with a foam precleaner ahead of the paper element, a two stage filtration setup that extends filter life in dusty mowing conditions. Kohler specifies a Champion RC12YC spark plug for this engine family, and oil capacity runs close to 1.9 to 2 quarts depending on the exact CV15 specification number, another reason the full spec code on the blower housing matters when ordering a maintenance kit. Following the maintenance schedule in the owner’s manual for oil changes, air filter service, and spark plug replacement goes a long way toward preventing the more involved repairs that come from deferred upkeep. Keeping the cooling fins around the cylinder free of grass clippings and debris helps this air cooled engine maintain a safe operating temperature during extended use under load. A quick check of the oil level and condition before each use catches a developing lubrication problem well before it turns into more serious internal engine wear. Replacing the fuel filter along with the air filter at the start of each season is a simple habit that reduces the odds of a mid season carburetor clog. Draining the fuel tank or adding a fuel stabilizer before long term storage prevents the ethanol varnish buildup that causes the majority of hard starting complaints once a machine comes back out of storage. Checking that the equipment this engine powers is properly balanced and free of debris buildup around moving parts also reduces unnecessary strain that can shorten engine life over time.

Most Replaced Parts on the CV15S/41562
Carburetor and Hard Starting Issues on the CV15S/41562
An engine that cranks but will not fire, or that stumbles at idle after sitting over winter, usually has a gummed up carburetor from stale, ethanol blended fuel. Confirm the spark plug fires and the air filter is clean before disassembling the carburetor, since either one alone can cause similar symptoms.
Spark Plug and Ignition Coil Problems on the CV15S/41562
Test the spark plug first whenever this engine will not fire, checking the gap against the 0.040 inch specification and looking for fouling from a rich fuel mixture. A fouled plug is far more common than a failed ignition coil, so ruling out the plug first avoids replacing a coil that was never the problem.
Air Filter and Airflow Issues on the CV15S/41562
A clogged air filter on this Command engine forces a rich fuel mixture, producing black exhaust smoke and reduced power under load. Inspect and replace the filter each season before adjusting or replacing carburetor components, since a dirty filter is a more frequent cause of poor running than an actual carburetor fault.
Electric Starter and No Crank Problems on the CV15S/41562
If the engine will not crank at all, check the 12 volt battery charge and starter connections before assuming the starter motor itself has failed. A weak battery or a corroded connection is a far more common cause of a no crank complaint than a genuine starter failure on this engine.

Why won’t the engine start after winter storage?
Stale, ethanol varnished fuel in the carburetor is the most common cause. Check the spark plug and air filter first, then inspect the carburetor if the engine still will not fire.
Do CV14 or CV460 parts fit this engine?
Many components are shared across the Command series 426cc engine family, but always confirm the exact model and specification number stamped on the blower housing before ordering.
What should I check if the engine won’t crank at all?
Check the 12 volt battery charge and starter wiring connections first, since a weak battery is a more common cause of a no crank complaint than a failed starter motor.
