high-quality fuel. Old or contaminated fuel can cause starting and running issues. Additionally
check the fuel filter and fuel lines for any blockages or damage. Clean or replace these components if necessary.

spark arrestor

it may need to be replaced to restore proper operation.

The carburetor plays a crucial role in the fuel mixture and engine performance. If the carburetor is dirty or clogged
it can cause the hedge trimmer to run poorly or stall. Remove the carburetor and clean it thoroughly
paying special attention to the jets and passages. If cleaning the carburetor does not resolve the issue
it may need to be adjusted or rebuilt by a qualified technician.

spark plug
ignition system
