To Next PageTo Next PageWhat to do if my Stiga WBE170 has irregular operation?
If your Stiga Engine is operating irregularly, consider these possible causes: * **Dirty spark plug:** Check the spark plug electrodes for dirt or incorrect gap. * **Incorrectly inserted spark plug cap:** Ensure the spark plug cap is firmly fitted. * **Clogged air filter:** Inspect and clean the air filter.
What to do if Stiga Engine does not start or starts badly?
If your Stiga engine doesn't start or starts badly, it could be due to a starting motor short circuit, so replace the starting motor. Another reason may be no earth, so check electrical cabling of earth wire. The coil could be faulty or the air gap too large, so check coil.
Why Stiga Engine uses a lot of oil?
If your Stiga engine is using a lot of oil, it could be due to several reasons. A faulty blow-by operation might be the cause, so check and/or replace the blow-by system and check the condition of the air filter. Poor piston ring seal can also lead to high oil consumption, so replace the rings. An excessive gap between the guide and the inlet valve stem could be the issue, requiring you to check and/or replace the valve. Lastly, a ring assembly error can cause excessive oil usage, so check the assembly of the rings.
What to do if Stiga Engine starts but does not run?
If your Stiga engine starts but doesn't continue to run, the tank cap may have a clogged breather pipe; in this case, clean or replace the cap. Another potential cause is insufficient pressure, so check correct valve operation, ensure the spark plug is secured, look for any cracks in the casing and check wear and tear of the piston rings. Also, the exhaust could be blocked, so check airflow through the exhaust system and replace if necessary.
Why is starting my Stiga Engine difficult and strains the rope?
If starting your Stiga engine is difficult and strains the rope, it could be due to oil in the combustion chamber, so clean the combustion chamber. Alternatively, there may be a pressure reducer fault, so check the pressure reducer and counterweights.
Why Stiga Engine starter motor does not run?
If the starter motor on your Stiga engine doesn't run, the battery might be flat, so check and recharge it. Ensure the battery is inserted correctly. There may be problems with the electric circuit and devices, so check all electrical connections and control devices. The starter motor itself could be electrically insufficient, requiring replacement. Finally, the starter micro switch may be faulty, so replace it.
What to do if Stiga Engine starter motor turns but cannot start the engine?
If the starter motor on your Stiga engine turns but the engine won't start, the battery may be insufficiently charged, so check and recharge it. It's also possible there is mechanical inefficiency of the starter motor, so dismantle the motor and clean the pinion zone. A broken flywheel could also be the cause, so check and/or replace the flywheel.
Why my Stiga Engine is overreving?
If the Stiga engine is overreving, the governor might be blocked due to breakage of the centrifugal assembly or external governor springs, or the governor might be dirty. You should check the entire governor system.
Why does my Stiga Engine judder?
If your Stiga engine judders, it could be due to loose engine screws, so tighten them. Another cause might be an off-center engine shaft, requiring replacement. Faulty engine timing can also cause juddering, so check wear and tear of the connecting rod of the engine shaft, replacing the shaft if necessary.
Why is my Stiga Engine difficult to start?
If you're having difficulty starting your Stiga Engine, there are several potential causes: * **No fuel:** Ensure the fuel tank is adequately filled. * **Old fuel or deposits:** Empty the fuel tank and refill with fresh fuel. * **Incorrect starting procedure:** Review and correctly perform the start-up procedure. * **Disconnected spark plug:** Make sure the spark plug cap is securely fitted. * **Wet or dirty spark plug:** Check the condition of the spark plug. * **Clogged air filter:** Inspect and clean the air filter. * **Incorrect oil:** Replace the current oil with a suitable oil for the season. * **Fuel evaporation (vapour lock):** Wait a few minutes and try starting again. * **Low battery:** Recharge the battery. * **Battery incorrectly inserted:** Ensure the batt...
