Why won't my Ryobi Trimmer engine start?
- LLisa WoodsJul 29, 2025
There are several reasons why your Ryobi Trimmer engine might not start. It could be due to the ignition switch being OFF, so ensure it is turned ON. The fuel tank might be empty, requiring a refill. You may not have pressed the primer bulb enough; try pressing it fully and slowly 5-7 times. The engine could be flooded; in this case, use the starting procedure with the choke lever in the RUN position. Old or improperly mixed fuel can also be a culprit, so drain the tank and add fresh fuel mixture. Lastly, a fouled spark plug can prevent starting, so try replacing or cleaning it.
