Reasons Why Stihl Hedge Trimmer Won T Start

No fuel

The most common reason for a Stihl hedge trimmer not starting is that there is no fuel in the tank. Make sure that the tank is full and that the fuel line is clear.

Bad spark plug

If the spark plug is bad, the engine will not be able to start. Check the spark plug for damage and replace it if necessary.

Dirty air filter

A dirty air filter can restrict airflow to the engine, causing it to stall or not start. Clean the air filter according to the manufacturer’s instructions.

Clogged fuel filter

A clogged fuel filter can prevent fuel from reaching the engine, causing it to stall or not start. Clean or replace the fuel filter according to the manufacturer’s instructions.

Corroded spark plug wire

A corroded spark plug wire can prevent the spark plug from firing, causing the engine to stall or not start. Inspect the spark plug wire for corrosion and replace it if necessary.

Engine flooded

If the engine is flooded, it will not start because the spark plug is being fouled by too much fuel. To clear the flood, turn the choke to the full open position and crank the engine until it starts. Once the engine starts, allow it to run for a few minutes before turning the choke back to the closed position.
