1. First check whether the engine oil and gasoline are newly added. Otherwise, they have been added more than three months ago. Oil and gasoline must be drained and replaced. Engine oil and gasoline are only valid for three months. Oil and gasoline used for more than three months have lost their viscosity and are useless.
2. Check if the engine oil and generator gasoline are filled. Otherwise, the generator will not turn on or start.
3. If the above conditions are met, check whether the spark plug ignites. Otherwise, remove the spark plug and put gasoline on it before reinstalling it to see if the generator fires. , it would be good if it started with the ignition.
(1) Check the fuel system
1. Too much gasoline is entering the engine's combustion chamber (stop for a few minutes and try to restart or remove the spark plug and wipe it clean).)
2. There is not enough fuel in the fuel tank, (add fuel to the tank)
3. The fuel filter is clogged, (clean the filter)
4. The carburetor is clogged, (clean the carburetor)
5. Air filter is dirty, (replace enrichment pump, enrichment pump tube and filter element)
6. The oil pipe is bent and there is no oil (adjust the length and direction)
7. The fuel type is incorrect or there is water in the fuel (replace with new fuel)
(2) Ignition system
1. Spark plug failure (clean carbon deposits from spark plug and adjust spark plug gap)
2. incorrect (adjust the gap between the valve and the ignition coil to be too large or too small)
3. The extinguishing switch is defective (replace the switch)
4. sufficient (replaceder the steering wheel)
5. Igniter fails (replace igniter)
6. The engine oil is not refilled or the quantity of engine oil is insufficient, triggering the oil alarm. system (added if necessary)
7. Extinguishing wire grounding (adjustment)
(3) Mechanical failure:
1. Valve clearances (properly adjust the intake and exhaust valves)
2. Cylinder seal is damaged (replace cylinder)
3. The valve seal is not good (repair or replace the valve)
< p >4. Cylinder, piston and piston ring wear (replace cylinder, piston, piston ring)5. The semi-circular flywheel key is cut, the ignition time is abnormal (replace the crankshaft and flywheel)
