Chainsaws are handy tools for various tasks, from cutting firewood to trimming trees. However, it can be frustrating when you’re ready to get to work, but your chainsaw won’t start. There can be several reasons why a chainsaw fails to start, ranging from simple issues to more complex problems. In this article, we’ll explore the common causes of a chainsaw starting troubles and provide step-by-step on how to start a chainsaw that won’t start to help you get your chainsaw up and running again.

How to Start a Chainsaw That Won't Start

1. Understanding Chainsaw Starting Issues

Before diving into the troubleshooting steps, it’s essential to understand some of the common problems that can prevent a chainsaw from starting. These issues include a defective spark plug, a clogged carburetor, a faulty ignition coil, a broken rewind spring, engine flooding with fuel, or inadvertently activating the choke in warm weather. By identifying and addressing these problems, you can increase the chances of starting your chainsaw successfully.

2. How to Start a Chainsaw That Won’t Start?

Troubleshooting Steps for a Chainsaw That Won’t Start. To effectively troubleshoot and start a chainsaw that refuses to start, follow these step-by-step instructions:

Step 1: Check the Spark Plug

The spark plug plays a crucial role in the combustion process. Start by inspecting the spark plug for signs of damage or dirt. Clean or replace it with a new one.

Step 2: Clean the Carburetor

A clogged carburetor can prevent fuel from reaching the engine. Carefully clean the carburetor, ensuring all the passages are debris-free. If cleaning doesn’t solve the issue, consider replacing the carburetor.

Step 3: Test and Replace the Ignition Coil

The ignition coil is responsible for generating the electrical spark needed for combustion. If there’s no spark, test the ignition coil and replace it if necessary.

Step 4: Ensure Proper Assembly of the Recoil Starter

Check the recoil starter assembly to ensure it is correctly assembled. Faulty assembly can prevent the starter cord from retracting properly. If needed, disassemble and reassemble the recoil starter.

Step 5: Replace the Rewind Spring

A broken rewind spring can cause the starter cord to fail to retract. Inspect the rewind spring and replace it if it’s damaged or worn out.

Step 6: Address Engine Flooding

If the engine is flooded with fuel, it won’t start. Check for signs of flooding and follow the steps to unflood the engine, such as removing and drying the spark plug, cleaning the air filter, and adjusting the choke lever.

Step 7: Deactivate the Choke in Warm Weather

In warm weather conditions, accidentally leaving the choke activated can make starting the chainsaw difficult. Ensure the choke is deactivated before starting the chainsaw.

Step 8: Check and Replace Fuel

Inspect the fuel in the chainsaw’s tank. If it’s deteriorated or contaminated, drain it and replace it with fresh fuel. Good fuel quality is vital for optimal chainsaw performance.

3. Seek Professional Assistance or Consider a Replacement

If you’ve followed all the troubleshooting steps and your chainsaw still won’t start, it may be time to seek professional assistance. A qualified technician can diagnose and fix more complex issues that may require specialized knowledge and tools. Alternatively, consider replacing your chainsaw with a new one if it is old or extensively damaged.

4. FAQ (Frequently Asked Questions)

How do you start a chainsaw when it is flooded?

If a chainsaw is flooded, the excess fuel in the engine can prevent it from starting. To remedy this, place the choke lever in the Off position, fully open the throttle trigger, and pull the starter rope multiple times. This process helps clear the excess fuel and allows proper starting.

Does a chainsaw need oil to start?

Yes, a chainsaw requires oil for lubrication, which is necessary for the smooth operation of its components. Chainsaws have two reservoirs: one for fuel and one for bar and chain oil. Before starting the chainsaw, it’s crucial to ensure the oil reservoir is adequately filled to avoid damage to the chain and bar.

What is the best way to start a chainsaw?

The best way to start a chainsaw is by following the manufacturer’s instructions specific to your model. Generally, it involves ensuring the On/Off switch is in the correct position, engaging the chain brake, priming the carburetor (if applicable), and pulling the starter rope with a firm, controlled motion. It’s essential to wear appropriate protective gear and position yourself correctly to maintain balance and control.

Why won’t my chainsaw start after sitting?

When a chainsaw has been idle for an extended period, several factors can contribute to difficulty starting it. Common culprits include stale fuel, clogged fuel lines, or a deteriorated spark plug. It’s advisable to drain the old fuel, replace it with fresh fuel, clean or replace the spark plug, and ensure proper fuel flow by inspecting and cleaning the fuel lines.

Why is it so hard to start a chainsaw?

Starting difficulties in chainsaws can be attributed to various factors. Common reasons include a defective spark plug, clogged carburetor, faulty ignition coil, broken rewind spring, engine flooding with fuel, or accidentally activating the choke in warm weather. Identifying and addressing these issues can help resolve starting problems.

Is there a trick to starting a chainsaw?

Starting a chainsaw requires following the proper procedure and taking necessary precautions. While there isn’t a specific “trick,” there are essential steps to ensure a successful start. These steps include positioning the chainsaw correctly, considering the fuel type, engaging the chain brake, utilizing the primer (if available), and following the manufacturer’s instructions.

Are there any preventive maintenance tips to keep my chainsaw starting reliably?

Yes, regular maintenance is crucial for a well-functioning chainsaw. Some preventive measures include cleaning or replacing the air filter, checking and tightening screws and nuts, maintaining proper oil levels, and following the manufacturer’s recommended maintenance schedule.

Can I start a chainsaw without engaging the chain brake?

Engaging the chain brake before starting the chainsaw is highly recommended for safety reasons. The chain brake helps prevent accidental chain rotation, reducing the risk of injuries.

What should I do if my chainsaw’s engine is flooded?

To unflood a flooded chainsaw engine, remove and dry the spark plug, clean or replace the air filter, and adjust the choke lever according to the manufacturer’s instructions.

Can using old or contaminated fuel affect my chainsaw’s starting ability?

Old or contaminated fuel can make it difficult for the chainsaw to start. Always use fresh, high-quality fuel to ensure optimal performance.

How often should I clean or replace the spark plug in my chainsaw?

It’s recommended to clean or replace the spark plug every 25 hours of chainsaw operation or at the start of each cutting season.
