Petrol engine tiller failure to start can be caused by a number of factors, here are six possible reasons:
Not enough gas: Make sure you have enough gas in the tank. If there is not enough gasoline in the tank, the rotary tiller cannot be started. Also, check that the gasoline is clean and not contaminated or aged.
Aged or damaged spark plug: The spark plug is part of the ignition system, if the spark plug is aged or damaged, the rotary tiller will not be able to ignite and start. Replacing spark plugs may require specialized skills and tools.
Damaged starter: The starter is one of the key components for starting the engine. If the starter is damaged, the rotary tiller cannot be started. If you hear a clicking sound or the starter won't turn, this could be a sign of a bad starter.
Oil pump failure: The oil pump is responsible for delivering gasoline from the fuel tank to the engine. If the oil pump fails, the rotary tiller will not start. Check that the oil pump is functioning properly, if it fails, it needs to be repaired or replaced.
Clogged fuel filter: The fuel filter is responsible for filtering the impurities in the fuel. If the fuel filter is blocked, gasoline cannot flow into the engine, and the rotary tiller cannot be started. The fuel filter needs to be cleaned or replaced.
Engine problems: Finally, a lawn mower that won't start could be due to a problem with the engine, such as a lack of lubricating oil or a lack of oxygen. Check that the engine's lubricating oil and air filter are clean, and make sure that all parts of the engine are functioning properly. If there is a problem, repairs or parts need to be replaced.
