What to do if Efco Trimmer engine will not start or runs only briefly?
- SStacy LloydAug 14, 2025
If your Efco Trimmer engine won't start or only runs for a few seconds, here's what you can do: 1. Check for a spark at the spark plug tip. If there's no spark, try again with a new spark plug (CMR7H). 2. If the engine is flooded, follow the procedure on page 28. If it still doesn't start, repeat the procedure with a new spark plug.
