Why won't my Senix GTS4QL-M2 engine start?

If your Senix Trimmer engine won't start, it could be due to several reasons. First, make sure the fuel tank isn't empty and fill it with fresh fuel if needed. Another possible cause is insufficient priming; try pressing the primer bulb 10 times. Also, old fuel (over 30 days) can be the culprit, so drain the tank and add fresh fuel. Lastly, a fouled spark plug can prevent starting, so consider replacing it.
