Why won't my chainsaw start after sitting for a long time?

Old fuel is one of the most common causes of starting problems. Fuel can degrade over time, clogging the carburettor and preventing proper combustion. Drain old fuel and refill with a fresh fuel mix.

Can a bad spark plug stop a chainsaw from starting?

Yes. A fouled, worn, or damaged spark plug can prevent ignition. Inspect the plug for carbon deposits, excessive wear, or incorrect gap settings and replace it if necessary.

How do I know if my chainsaw air filter is clogged?

Remove the air filter and hold it up to a light source. If little or no light passes through, the filter is clogged and should be cleaned or replaced.

What should I check first if my chainsaw won't start?

Start with the basics: check the fuel quality, inspect the spark plug, clean the air filter, and verify that the correct starting procedure is being followed.

When should I take a chainsaw to a professional for repair?

If you've checked fuel, spark, air filtration, carburettor function, and compression but the chainsaw still won't start, professional diagnosis may be required to inspect the ignition system, piston, rings, or seals.
