Echo Lawn mower starts then stalls
If your Echo lawn mower starts then stalls, the problem is usually fuel-related, and the carburetor is the first place to look. Old gas can leave sticky deposits inside the carburetor, restricting fuel flow so the engine starts, runs briefly, then dies. In many cases, cleaning the carburetor with carburetor cleaner will help, but if buildup is severe you may need a carburetor repair kit or a complete carburetor replacement. Another common cause is a clogged fuel cap vent. When the vent plugs up, the tank cannot pull in air, a vacuum forms, and fuel stops reaching the carburetor, causing the lawn mower starts then dies symptom. Try loosening the fuel cap slightly to see if the engine keeps running. If it does, replace the cap. Old or bad gasoline can create the same stalling problem and should be drained and replaced with fresh fuel. If the fuel system checks out, inspect the spark plug for wear, carbon buildup, or damage, and test it with a spark plug tester.

01 - Echo Lawn Mower Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the lawn mower 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 cause the engine to stall. 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 - Echo Lawn Mower Fuel Cap
As fuel is consumed by the engine, the level in the fuel tank lowers. To make up for this, the fuel cap uses a small vent to allow air to enter the tank. If the fuel cap vent is clogged, air won’t be able to enter the tank and a vacuum or “vapor lock” will occur. This stops the flow of fuel to the carburetor causing the engine to stall. To determine if the fuel cap vent is clogged, try slightly loosening the cap and then starting the engine. If loosening the fuel cap allows the engine to stay running it is likely clogged and will need to be replaced.

05 - Echo Lawn Mower 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.
