Echo Lawn mower is hard to start
If your Echo lawn mower is hard to start, the most common problem is a clogged carburetor caused by old fuel turning sticky and restricting fuel flow. This is one of the top reasons an Echo lawn mower takes many pulls to start or feels like a small engine hard starting issue. Start by cleaning the carburetor with carburetor cleaner. If that does not solve it, rebuild it with a carburetor repair kit or replace the carburetor. A cracked primer bulb is another likely cause because it can let air into the fuel system and make the engine difficult to start. Old or bad gasoline left in the carburetor float bowl can create the same hard starting condition. After that, check the spark plug for wear, damage, or heavy carbon buildup, and use a spark plug tester to confirm it produces a strong spark while cranking. If fuel delivery is still weak, inspect the fuel pump, including the pulse port line, diaphragm, and check valves.

01 - Echo Lawn Mower Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the hedge trimmer 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 make the engine hard to start. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

02 - Echo Lawn Mower Primer Bulb
Over time, the rubber of the primer bulb can become brittle and cracked. If the primer bulb is cracked, air will get into the fuel system and cause the engine not to run properly. If the primer bulb is cracked, replace it.

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.

06 - Echo Lawn Mower Fuel Pump
The fuel pump has three ports: the gas in port, the gas out port, and the pulse port. The pulse port is connected to the engine crankcase by a small rubber tube. As the engine runs, air inside the crankcase alternately pressurizes and depressurizes the air in the tube. This pressurized air moves a diaphragm inside the pump and pumps the gas. If the engine oil is overfilled, oil can enter the pulse port line, preventing it from working properly. The fuel pump also has two small check valves on the input and output ports. The check valves prevent fuel from reentering the gas tank. These check valves can fail. To determine if...
