Dixon Lawn mower won't start
If your Dixon lawn mower won't start, start with the most common failure points before you assume the engine has a major problem. A worn or fouled spark plug is the first thing to check. Look for a cracked porcelain insulator, burned electrode, or heavy carbon buildup, and use a spark plug tester to confirm the plug is producing a strong spark while cranking. If the spark plug checks out, the next likely issue is a clogged carburetor caused by stale fuel, varnish, or debris in the carburetor float bowl. Cleaning the carburetor with carburetor cleaner may get the mower running again, but in some cases you will need a carburetor repair kit or a complete carburetor replacement. Old or bad gasoline can cause the same lawn mower not starting symptom, so draining contaminated fuel is often part of the fix. On Dixon riding mower models, a faulty start switch can also keep the engine from cranking properly, and a bad fuel pump may prevent fuel delivery.

01 - Dixon 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 - Dixon 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 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.

06 - Dixon 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...
