A chainsaw that stalls frequently or idles unevenly can disrupt your work and lead to frustration.
Causes
Poor idling is often caused by a clogged air filter, a dirty carburetor, or incorrect carburetor settings.
Old or poor-quality fuel can also impact engine performance, leading to idling problems.
Fixes
Start by cleaning or replacing the air filter and carburetor. Adjust the carburetor settings according to the manufacturer’s guidelines, and always use fresh, high-quality fuel.

- Avoid cutting wood with dirt or debris on it.
- Inspect the chain for damage and replace it if necessary.
8. Spark plug failure
A common issue with Dolmar chainsaws is spark plug failure, which can lead to starting problems or poor engine performance.
The spark plug is essential for igniting the fuel-air mixture, and when it fails, your chainsaw won’t function properly.
Causes
Spark plug failure can happen due to dirt, carbon buildup, or natural wear over time. Faulty spark plugs may also occur if the engine is running too rich or too lean.
Fixes
Start by inspecting the spark plug for damage or buildup. Clean it if dirty, or replace it if worn out.
Always ensure you’re using the correct spark plug type for your Dolmar chainsaw for optimal performance..
9. Carburetor issues
Carburetor problems are a common reason your Dolmar chainsaw might not run properly.
If the engine sputters, stalls, or refuses to start, a clogged or misadjusted carburetor could be the culprit.
Causes
- Dirt or debris clogging the carburetor.
- Improper carburetor adjustment.
- Stale or bad fuel causing buildup.
Fixes
- Clean the carburetor thoroughly to remove any blockages.
- Adjust the carburetor settings according to the user manual.
- Replace old fuel with fresh, high-quality gasoline. If the problem persists, consider consulting a professional or replacing the carburetor..
10. Exhaust blockage
Over time, your Dolmar chainsaw’s exhaust can get clogged with carbon deposits, restricting airflow and reducing performance.
Causes:
- Carbon buildup in the muffler or spark arrestor screen.
- Using low-grade fuel or improper oil mixtures.
