Husqvarna Chainsaw Flooded? How to Restart It (Pro Tips)

“Flooding is a common issue, especially with two-stroke engines like those in many Husqvarna chainsaws. Understanding why it happens and knowing the correct restart procedure can save you a lot of frustration and downtime,” – John Stone, Certified Arborist and Small Engine Mechanic.

Husqvarna Chainsaw Flooded? How to Restart It (Pro Tips)

Ah, the dreaded flooded chainsaw. There’s nothing quite as frustrating as pulling and pulling on that starter cord, only to be met with a sputtering, stubborn silence. Especially when you’re in the middle of a big job, like bucking firewood for the winter or felling a tree that’s threatening your shed. I’ve been there countless times. I remember one particularly cold November day, out in the back forty, wrestling with a flooded saw as the sun dipped below the horizon. That experience, along with many others, taught me the crucial steps for getting a flooded Husqvarna chainsaw back up and running quickly.

Understanding Chainsaw Flooding: The Root Cause

Before we dive into the restart procedure, it’s essential to understand why your chainsaw floods in the first place. A flooded engine simply means there’s too much fuel in the cylinder, preventing the air-fuel mixture from igniting properly. Here are the most common culprits:

• Over-Priming: This is the most frequent cause. The primer bulb pumps fuel directly into the carburetor. Too many pumps, and you’ve got more fuel than the engine can handle. I’ve seen this happen most often when people are overly cautious, especially when the saw is cold.
• Incorrect Starting Procedure: Following the correct starting procedure is crucial. If you engage the choke incorrectly or pull the starter cord too many times with the choke on, you’re likely to flood the engine.
• Choke Problems: A faulty choke mechanism that doesn’t open fully can restrict airflow and lead to flooding.
• Warm Engine Starting: Attempting to start a warm engine with the choke engaged is a surefire way to flood it. A warm engine needs less fuel to start.
• Carburetor Issues: A malfunctioning carburetor can deliver too much fuel, even if you’re following the correct starting procedure. This is a less common but more serious problem. I once had a carburetor that would constantly leak fuel, leading to persistent flooding issues until I replaced it.
• Tipped Chainsaw: If you tip the chainsaw on its side or upside down, fuel can leak into the cylinder, causing it to flood.

The Step-by-Step Restart Procedure for a Flooded Husqvarna Chainsaw

Okay, your chainsaw is flooded. Don’t panic. Here’s a proven method for getting it running again:

1. Safety First: Before you do anything, make sure the chainsaw is on a stable surface and the chain brake is engaged. This prevents accidental starting and potential injury. I always double-check the chain brake, even when I’m in a hurry.
2. Clear the Area: Ensure there are no flammable materials nearby and that you’re in a well-ventilated area. Gasoline fumes can be dangerous.
3. Turn Off the Ignition (If Possible): Some Husqvarna models have a combined choke/stop switch. Ensure it’s in the “off” or “stop” position. This prevents the engine from trying to start while you’re clearing the flood.
4. Remove the Spark Plug: This is the crucial step for clearing the excess fuel. Use the spark plug wrench that came with your chainsaw to remove the spark plug. Be careful not to damage the spark plug or the surrounding area.
5. Inspect the Spark Plug: Examine the spark plug. If it’s wet with fuel, that confirms the engine is flooded. Clean the spark plug with a clean, dry cloth or wire brush. If the spark plug is fouled (covered in carbon deposits), consider replacing it. A new spark plug can make a significant difference in starting performance.
6. Purge the Cylinder: With the spark plug removed, pull the starter cord several times (5-10 pulls) to purge the excess fuel from the cylinder. You might see fuel spray out of the spark plug hole – that’s a good sign. This step is essential for removing the excess fuel that’s preventing combustion.
7. Dry the Spark Plug: Thoroughly dry the spark plug. A wet spark plug won’t ignite the air-fuel mixture.
8. Reinstall the Spark Plug: Carefully reinstall the spark plug and tighten it securely with the spark plug wrench.
9. Starting Procedure (No Choke): This is where it gets tricky. Now, try starting the chainsaw without using the choke. Set the throttle to the “fast idle” position (usually indicated by a half-throttle symbol). Pull the starter cord firmly and repeatedly until the engine starts. It might take several pulls, so be patient.
10. Adjust Throttle: Once the engine starts, let it idle for a few seconds, then gradually increase the throttle. If the engine stalls, repeat steps 9 and 10.
11. Troubleshooting: If the chainsaw still doesn’t start after several attempts, there might be another issue. See the troubleshooting section below.

Preventing Chainsaw Flooding: Best Practices

Prevention is always better than cure. Here are some best practices to minimize the risk of flooding your Husqvarna chainsaw:

• Prime Sparingly: Only prime the engine a few times, especially when it’s warm. Refer to your owner’s manual for the recommended number of primes. I usually prime twice when the saw is cold and not at all when it’s warm.
• Follow the Correct Starting Procedure: Adhere strictly to the starting procedure outlined in your owner’s manual. This usually involves engaging the choke for cold starts and disengaging it once the engine starts.
• Warm Engine Starts: When starting a warm engine, never use the choke. Simply set the throttle to the fast idle position and pull the starter cord.
• Check the Choke Mechanism: Periodically inspect the choke mechanism to ensure it’s functioning correctly. Make sure it opens and closes fully.
• Use Fresh Fuel: Old or stale fuel can cause starting problems and increase the risk of flooding. Use fresh fuel that’s no more than 30 days old. I always use fuel stabilizer to extend the life of my fuel.
• Store the Chainsaw Properly: Store the chainsaw in a level position to prevent fuel from leaking into the cylinder.
• Regular Maintenance: Regular maintenance, including cleaning or replacing the air filter and spark plug, can prevent flooding and other engine problems.

Troubleshooting: When the Restart Procedure Fails

Sometimes, even after following the restart procedure, your chainsaw might still refuse to start. Here are some common troubleshooting steps:

• Check the Spark Plug: If the spark plug is fouled or damaged, replace it with a new one. A faulty spark plug can prevent the engine from starting, even if it’s not flooded.
• Check the Fuel Filter: A clogged fuel filter can restrict fuel flow and cause starting problems. Replace the fuel filter if it’s dirty or clogged. I usually replace my fuel filter every year.
• Check the Air Filter: A dirty air filter can restrict airflow and lead to a rich fuel mixture, increasing the risk of flooding. Clean or replace the air filter as needed.
• Check the Carburetor: If you suspect a carburetor problem, you might need to have it professionally cleaned or rebuilt. Carburetor issues are best left to experienced mechanics.
• Check the Ignition System: A faulty ignition system can prevent the engine from starting. This is a more complex issue that might require professional diagnosis and repair.

Chainsaw Maintenance Costs: A Budgeting Perspective

Owning a chainsaw comes with ongoing maintenance costs. Understanding these costs can help you budget for your wood processing projects and avoid unexpected expenses. Here’s a breakdown of common chainsaw maintenance costs:

• Fuel: Chainsaws typically use a mixture of gasoline and two-stroke oil. The cost of fuel varies depending on the price of gasoline and the type of oil you use. I typically spend around $20-$30 per month on fuel for my chainsaw, depending on how much I’m using it.
• Two-Stroke Oil: High-quality two-stroke oil is essential for lubricating the engine and preventing wear. I recommend using a synthetic two-stroke oil for optimal performance and longevity. The cost of two-stroke oil varies depending on the brand and type. I usually pay around $15-$20 for a quart of synthetic two-stroke oil.
• Chain Oil: Chain oil lubricates the chain and bar, reducing friction and wear. Use a high-quality chain oil specifically designed for chainsaws. The cost of chain oil varies depending on the brand and type. I typically spend around $10-$15 per month on chain oil.
• Chain Sharpening: A sharp chain is essential for efficient and safe cutting. You can sharpen the chain yourself using a file or chain grinder, or you can take it to a professional. The cost of professional chain sharpening typically ranges from $10-$20 per sharpening. I prefer to sharpen my own chains using a file, which saves me money in the long run.
• Chain Replacement: Chains eventually wear out and need to be replaced. The cost of a new chain depends on the size and type of chain. I usually pay around $20-$40 for a new chain.
• Bar Replacement: The chainsaw bar also wears out over time and needs to be replaced. The cost of a new bar depends on the size and type of bar. I typically pay around $30-$50 for a new bar.
• Spark Plug Replacement: Spark plugs should be replaced periodically to ensure optimal engine performance. The cost of a new spark plug is typically around $5-$10.
• Air Filter Replacement: Air filters should be cleaned or replaced regularly to prevent engine problems. The cost of a new air filter is typically around $5-$10.
• Fuel Filter Replacement: Fuel filters should be replaced periodically to ensure proper fuel flow. The cost of a new fuel filter is typically around $5-$10.

Fuel and Oil Costs: A Deeper Dive

Fuel and oil are significant ongoing expenses for chainsaw owners. Understanding the factors that influence these costs can help you optimize your budget.

• Fuel Type: Chainsaws typically require gasoline with an octane rating of 87 or higher. Using premium gasoline is generally not necessary and won’t improve performance.
• Two-Stroke Oil Ratio: Most Husqvarna chainsaws require a fuel-to-oil ratio of 50:1. This means you need to mix 50 parts of gasoline with 1 part of two-stroke oil. Always use the correct fuel-to-oil ratio to prevent engine damage.
• Fuel Stabilizer: Adding fuel stabilizer to your fuel can extend its shelf life and prevent it from breaking down. This is especially important if you don’t use your chainsaw frequently.
• Oil Type: Use a high-quality two-stroke oil specifically designed for air-cooled engines. Synthetic two-stroke oils offer superior lubrication and protection compared to conventional oils.
• Chain Oil Viscosity: Use a chain oil with the correct viscosity for your chainsaw and the ambient temperature. Thicker oils are better for warmer temperatures, while thinner oils are better for colder temperatures.
• Bulk Purchases: Buying fuel and oil in bulk can save you money in the long run. Consider purchasing a large container of two-stroke oil and a fuel can that you can fill up at the gas station.

Data Point: According to the U.S. Energy Information Administration (EIA), the average price of gasoline in the United States in 2023 ranged from \$3.40 to \$3.80 per gallon. The price of two-stroke oil can vary widely depending on the brand and type, but you can expect to pay around \$15-\$25 per quart for a high-quality synthetic oil.

Here’s a broader look at the expenses involved in preparing firewood or processing timber:

• Timber Purchase or Harvesting Costs: If you’re purchasing timber, the cost will depend on the species, quality, and volume of wood. If you’re harvesting timber from your own property, you’ll need to factor in the cost of permits, if required, and the time and labor involved in felling and transporting the trees.
• Land Access: If you don’t own the land where you’re harvesting wood, you might need to pay for access rights.
• Transportation Costs: Transporting logs or firewood can be a significant expense, especially if you’re hauling them long distances. Consider the cost of fuel, vehicle maintenance, and any rental fees for trailers or trucks.
• Splitting Costs: If you’re preparing firewood, you’ll need to split the logs. You can split them manually with a maul and wedge, or you can use a log splitter. Log splitters can be rented or purchased.
• Drying Costs: Firewood needs to be dried before it can be burned efficiently. The drying process can take several months or even years, depending on the species of wood and the climate. You’ll need to factor in the cost of storing the firewood in a dry, well-ventilated location.
• Labor Costs: If you’re hiring someone to help you with wood processing, you’ll need to pay them for their time and labor.
• Equipment Costs: In addition to the chainsaw, you might need to purchase or rent other equipment, such as a log splitter, trailer, or safety gear.

Case Study: I once helped a friend prepare firewood for the winter. We harvested dead trees from his property, split the logs with a rented log splitter, and stacked the firewood in a shed to dry. The total cost of the project was around \$500, including the log splitter rental, fuel, and chain oil. However, he estimated that he saved around \$1000 by preparing his own firewood instead of buying it from a supplier.

Optimizing Wood Processing Costs: Practical Tips

Here are some practical tips for optimizing your wood processing costs:

• Harvest Wood Sustainably: If you’re harvesting wood from your own property, practice sustainable forestry techniques to ensure a long-term supply of timber.
• Buy Wood in Bulk: Buying wood in bulk can often save you money compared to buying it in smaller quantities.
• Rent Equipment Instead of Buying: If you only need a log splitter or other equipment occasionally, consider renting it instead of buying it.
• Maintain Your Equipment Regularly: Regular maintenance can extend the life of your equipment and prevent costly repairs.
• Dry Firewood Properly: Properly drying firewood can improve its burning efficiency and reduce the amount of wood you need to burn.
• Shop Around for Supplies: Compare prices from different suppliers to find the best deals on fuel, oil, and other supplies.
• Do It Yourself: Performing some of the wood processing tasks yourself can save you money on labor costs.
• Consider Alternative Fuel Sources: Explore alternative fuel sources, such as wood pellets or biobricks, which might be more cost-effective than firewood in some areas.

Understanding Timber Prices and Fuelwood Market Rates

Timber prices and fuelwood market rates can vary significantly depending on location, species, and demand. Here’s an overview of these factors:

• Timber Prices: Timber prices are influenced by factors such as the species of wood, the quality of the logs, the accessibility of the timber, and the overall demand for wood products. Prices can fluctuate significantly depending on market conditions.
• Fuelwood Market Rates: Fuelwood market rates depend on factors such as the species of wood, the dryness of the wood, the quantity purchased, and the local demand for firewood. Prices can vary significantly depending on the region and the time of year.

Data Point: According to the USDA Forest Service, the average stumpage price (the price paid for standing timber) for hardwood sawtimber in the United States in 2022 was around \$200 per thousand board feet. The average price for softwood sawtimber was around \$150 per thousand board feet. However, these prices can vary significantly depending on the species and location.

Data Point: The average price per cord of firewood in the United States in 2023 ranged from \$200 to \$400, depending on the region and the species of wood. Prices are typically higher in urban areas and during the winter months.

Chainsaw Safety: A Non-Negotiable Cost

While not a direct monetary cost, prioritizing chainsaw safety is paramount. Injuries can lead to significant medical expenses, lost work time, and potential long-term health issues. Always invest in proper safety gear, including:

• Chainsaw Chaps: These protect your legs from accidental cuts.
• Eye Protection: Safety glasses or a face shield prevent flying debris from injuring your eyes.
• Hearing Protection: Earplugs or earmuffs protect your hearing from the loud noise of the chainsaw.
• Gloves: Gloves provide a better grip and protect your hands from cuts and abrasions.
• Steel-Toed Boots: Steel-toed boots protect your feet from falling logs and accidental cuts.
• Helmet: A helmet protects your head from falling branches and other hazards.

Data Point: According to the Centers for Disease Control and Prevention (CDC), approximately 30,000 people are treated in emergency rooms each year for chainsaw-related injuries.

Chainsaw Calculations: Board Feet and Cords

Understanding how to calculate the volume of logs in board feet or cords is essential for estimating timber yields and pricing.

• Board Foot: A board foot is a unit of volume equal to 144 cubic inches. It’s commonly used to measure the volume of lumber.
• Cord: A cord is a unit of volume equal to 128 cubic feet. It’s commonly used to measure the volume of firewood.

Formulas:

• Board Feet (Doyle Log Rule): (Diameter in inches – 4)² x Length in feet / 16
• Cords: Volume in cubic feet / 128

Example: A log that is 12 inches in diameter and 10 feet long has a volume of approximately 64 board feet (using the Doyle Log Rule). A pile of firewood that is 8 feet long, 4 feet wide, and 4 feet high has a volume of 128 cubic feet, or 1 cord.

Drying Time Estimation: Moisture Content Matters

The drying time for firewood depends on the species of wood, the climate, and the moisture content of the wood. Here’s a general guideline:

• Softwoods: Softwoods typically dry faster than hardwoods. They usually take 6-12 months to dry.
• Hardwoods: Hardwoods can take 12-24 months or longer to dry.

Factors Affecting Drying Time:

• Species of Wood: Some species of wood dry faster than others.
• Climate: Warm, dry climates are ideal for drying firewood.
• Moisture Content: The higher the initial moisture content of the wood, the longer it will take to dry.
• Stacking Method: Stacking firewood in a way that allows for good airflow can speed up the drying process.
• Sun Exposure: Exposing firewood to direct sunlight can also speed up the drying process.

Data Point: Firewood should have a moisture content of 20% or less before it is burned. You can use a moisture meter to measure the moisture content of your firewood.
