Dixon Lawn mower smoking
If your Dixon lawn mower is smoking and blowing black smoke, the engine is usually running rich, which means the carburetor is letting in too much fuel. The most likely cause is a carburetor float stuck open, followed closely by a choke stuck closed, both of which throw off the air-fuel mixture and can lead to a mower running rich. On many Dixon models, a worn or dirty carburetor can often be fixed with the right carburetor repair kit, though in some cases replacing the full carburetor is the better move. If your lawn mower engine smoking problem starts suddenly or gets worse under load, checking the carburetor first makes the most sense. Look for fuel control issues inside the carburetor body, especially around the float and choke operation, since those are the common trouble spots behind a lawn mower smoking complaint. RepairClinic makes it easier to match the fix to your exact machine. Just enter your model number on RepairClinic.com to find the exact Dixon carburetor or carburetor repair kit that fits your specific lawn mower.
01 - Carburetor is Letting Too Much Fuel In
If the lawn mower engine produces black smoke, this indicates that the carburetor is getting too much fuel (or "running rich"). If the carburetor float is stuck open, the engine will get too much fuel. Similarly, if the carburetor choke is stuck closed, the lawn mower engine will not be able to draw in enough air to create the proper air-fuel mixture.
