What to do if my Echo CS-620P engine cranks but has no spark at the plug?
- UuhinesJul 26, 2025
If your Echo Chainsaw engine cranks but there's no spark at the plug, it could be due to an incorrect spark gap, carbon buildup, fuel fouling, or a defective spark plug. Adjust the gap to 0.6-0.7 mm (0.024 to 0.028 in.), clean or replace the plug to remove carbon or fuel, or replace the spark plug entirely.
