Snapper Pressure washer won't start
If your Snapper gas pressure washer won't start, begin with the spark plug, the most likely cause. Check for a cracked porcelain insulator, burned electrode, heavy carbon buildup, or no strong spark while the engine is cranking. If the spark plug tests good, inspect the carburetor. Stale or ethanol-blended fuel left in the carburetor is one of the most common causes of seasonal equipment problems, and the resulting sticky residue can clog the main jet, needle valve, or other passages. Clean the carburetor with carburetor cleaner, or replace it if cleaning does not restore fuel flow. A defective ignition coil can also prevent the spark plug from receiving voltage, so test the coil after confirming the plug works. Finally, inspect the flywheel key if the engine stopped suddenly or struck a hard object. A sheared flywheel key can disrupt ignition timing and cause a pressure washer not starting condition. These checks can help explain why your pressure washer will not start, why your pressure washer won't turn on, or why a power washer won't start.

01 - Snapper Pressure Washer Spark Plug
Inspect the spark plug for signs of wear or damage. If the porcelain insulator is cracked, an electrode is burned away or damaged, or there is heavy carbon buildup at the electrode, replace the spark plug. To determine if the spark plug is defective, use a spark plug tester. You should see a strong spark between the tester’s terminals when the engine is cranking. If there is no spark, this indicates that the spark plug is defective and should be replaced.

02 - Snapper Pressure Washer Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

03 - Snapper Pressure Washer Ignition Coil
The ignition coil sends voltage to the spark plug while the engine is running. If the ignition coil is defective, the engine may not start. Before replacing the ignition coil, ensure that the spark plug is working properly. If you have confirmed that the spark plug is working properly, test the ignition coil with an ignition coil tester. If the ignition coil is defective, replace it.

04 - Snapper Pressure Washer Flywheel Key
the flywheel key might have sheared in half. The flywheel key is a small metal piece which fits into the crankshaft and engages with the flywheel. If the engine stops suddenly due to the pressure washer hitting a hard object, the flywheel key breaks in half to prevent damage to the engine. To determine if the flywheel key is broken, remove the flywheel from the engine and inspect the flywheel key. If the flywheel key is broken, replace it.
