Snapper Small engine hard to start

If your Snapper small engine is hard to start, begin with the spark plug. A worn, cracked, carbon-fouled, or damaged spark plug can produce a weak spark or no spark, causing engine starting problems and making the engine hard to start, especially when cold. Test the plug while cranking the engine and replace it if it does not produce a strong spark. Next, check the carburetor. A clogged carburetor can restrict fuel flow, while a choke that does not close properly can deliver too much fuel. Stale or ethanol-blended fuel left in the carburetor is one of the most common root causes on seasonal equipment and may require carburetor cleaning or replacement. Also inspect the fuel cap. A clogged vent prevents air from entering the fuel tank, allowing pressure to build and causing the engine to start poorly or not start at all. Loosening the cap slightly during a test can help confirm the problem. Enter your Snapper model number to find the exact replacement spark plug, carburetor, or fuel cap for your engine.

01 - Snapper 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 Carburetor

The engine may be getting too much fuel or not enough fuel. This is usually due to the carburetor not working properly. If the carburetor is clogged, the engine won't get enough fuel. If the carburetor choke isn't closing properly, the engine may get too much fuel.

03 - Snapper Fuel Cap

As fuel is consumed, the pressure in the gas tank rises. To relieve this pressure, the gas cap uses a small vent to allow air to enter the gas tank. If the gas cap vent is clogged, air won’t be able to enter the gas tank, and the pressure in the tank will begin to rise. When the pressure in the gas tank exceeds the pressure in the engine, the engine may be hard to start. To determine if the gas cap vent is clogged, try slightly loosening the gas cap and then starting the engine. If the loosening the gas cap allows the engine to stay running, this indicates that the gas cap vent is clogged. If the gas cap vent is clogged, r...eplace the gas cap.
