How To Start A Stihl Chainsaw Without Flooding It?

The sweet sound of a revving chainsaw… or is it more like the agonizing gurgle of a flooded engine? 

If your Stihl chainsaw has been giving you more trouble than a teenage drama queen, we’ve got the fix you’ve been desperately searching for.

How To Start A Stihl Chainsaw Without Flooding It?

Are Stihl chainsaws prone to starting chainsaw flooding?

Yes, Stihl chainsaws are prone to flooding. Excessive use of the choke can cause Stihl chainsaws to be susceptible to flooding. When the choke is overused, an abundance of fuel accumulates in the cylinder, leading to the spark plug electrodes getting wet. As a result, the spark plug is unable to ignite the fuel vapor, causing starting difficulties.

Flooding can occur if the choke is left engaged for an extended period or if the chainsaw is repeatedly started with the choke on. It’s important to strike a balance and avoid drowning your engine in fuel. Remember, moderation is the key to success.

While Stihl chainsaws may be prone to flooding, it’s worth noting that this is a common issue faced by many chainsaw brands, not exclusive to Stihl alone. 

So, whether you’re wielding a Stihl or another make, understanding the risks of flooding and adopting the right starting techniques will help you avoid frustrating setbacks and keep your chainsaw running smoothly.

How to start a stihl chainsaw without flooding it?

To start a Stihl chainsaw without flooding it, follow these steps:

1. Ensure you have the correct fuel mixture

Stihl chainsaws, like the MS-250, are two-cycle units that require mixed gas. The recommended ratio is 50 parts gas to 1 part oil. For example, if you have a two-and-a-half-gallon gas tank, you’ll need two-and-a-half bottles of mixed gas.

2. Fill the oil reservoir

Locate the oil reservoir at the front of the chainsaw and fill it up to the indicated line. It’s important to note that the gas and oil levels will deplete at approximately the same rate, so if you need to top off the gas, remember to also check and refill the oil.

3. Fill the gas tank

The gas tank is located at the back of the chainsaw. Stihl chainsaws typically have easy-lock caps, so insert the gas can nozzle, twist, and push down to securely seal the cap.

4. Prepare for starting

Ensure that the chain brake is off, and set the choke to the full position. This will enrich the fuel mixture for easier starting.

5. Start the chainsaw

Pull the starter cord a few times until you hear the engine sputter. Once you hear the sputtering, move the choke to the half-choke or run position. Give a few more pulls on the starter cord, and the chainsaw should start up smoothly.

What Are Some Ways To Maintain A Stihl Chainsaw, especially against flooding?

Maintaining your Stihl chainsaw regularly will ensure smooth operation and prevent flooding. Here are some essential maintenance tips for your Stihl chainsaw:

1. Regular cleaning and maintenance

After each use, take the time to clean your chainsaw thoroughly. Wipe away any wood debris and make sure no particles are clogging the air filter or carburetor. Keeping these components clean will promote proper airflow and fuel delivery.

2. Proper fuel mixture

When mixing gas and oil for your Stihl chainsaw, be cautious not to overdo it with the oil. Most models require a fuel mixture of 50 parts gasoline to 1 part oil. Excessive oil can contribute to flooding issues down the line, so measure your fuel mixture carefully.

3. Avoid excessive use of the choke

Excessive choking can lead to flooding, so be mindful of how long you keep the choke engaged. For most Stihl chainsaws, leaving the choke on for more than 3 or 4 pulls can result in flooding. Use the choke sparingly to prevent this problem.

4. Unflood the engine

If your chainsaw does flood, there are a couple of methods to resolve the issue. One approach is to repeatedly pull the starter cord while the master control lever is in Idle or Warm Start mode. Another trick is to let the chainsaw sit in the sun for a few hours, as the heat can aid in evaporating excess fuel. Actively clearing the cylinder of fuel can help unflood the engine within minutes.

5. Regular maintenance

An important part of preventing flooding and other problems is regular chainsaw maintenance. This includes tasks such as cleaning the air filter, checking the spark plug, and ensuring that the chain is properly lubricated. You can prevent flooding and other frustrating issues by keeping on top of these maintenance tasks.

How Long Should A Stihl Chainsaw Last?

The expected lifespan of a Stihl chainsaw is typically around five years, which translates to approximately 1800-2200 hours of usage. However, it’s important to note that the actual longevity of a chainsaw can vary based on several factors, including the brand, manufacturer, maintenance practices, and storage conditions.

A chainsaw’s lifespan is dependent on the aforementioned factors, with maintenance being an important factor. Regular maintenance, such as oil changes and sharpening, can potentially extend the life of a Stihl chainsaw.

To improve the overall life expectancy of your chainsaw, prioritizing regular maintenance is essential. Among these activities are inspecting the spark plug, cleaning the air filter, and lubricating the chain. Maintaining your Stihl chainsaw can extend its lifespan and minimize flooding issues.

Conclusion

In conclusion, starting a Stihl chainsaw without flooding requires following a few simple steps. By properly priming the engine, setting the choke correctly, and pulling the starter cord gently, users can avoid flooding the engine and ensure a smooth and efficient start.

FAQs

Why is it important not to flood a Stihl chainsaw? 

Flooding a Stihl chainsaw can lead to starting issues, increased fuel consumption, reduced engine performance, and potential damage to the spark plug or other engine components.

Can leaving a Stihl chainsaw idling overnight unflood the cylinder?

Yes, leaving the cylinder idling overnight helps unflood it. By allowing the excess fuel to evaporate through prolonged idling, you increase the chances of a successful start-up when you attempt to use the chainsaw again.

How long does it take for a flooded Stihl chainsaw to unflood?

The time required for a flooded Stihl chainsaw to unflood can vary. By actively clearing the cylinder of fuel, it can take just a few minutes to resolve the flooding issue. Leaving the chainsaw to stand in the sun for a few hours or idling it overnight can also aid in unflooding the cylinder.
