How to troubleshoot a Troy-Bilt TB20CS Trimmer that will not start?
- TTara LopezJul 25, 2025
If your Troy-Bilt Trimmer engine won't start, possible causes include an empty fuel tank (fill it with properly mixed fuel), a primer bulb that wasn't pressed enough (press it fully and slowly 10 times), or a flooded engine (squeeze the trigger and pull the starter rope). Other potential issues are old or improperly mixed fuel (drain and add fresh fuel), a fouled spark plug (replace or clean it), or a plugged spark arrestor (clean or replace it). Also, consider the outside temperature: if it's below 40ºF, pull the starter rope 10-15 times; if it's above 90ºF, squeeze the throttle control and pull the starter rope.
