266 Husqvarna Chainsaw Issues (Expert Fixes for Firewood Cutting)

Alright, let’s dive into the heart of the matter – troubleshooting and optimizing the Husqvarna 266 chainsaw for serious firewood cutting.

“The old saw sang a different tune that day,” I remember thinking, staring down at my trusty Husqvarna 266. It had been a faithful companion for years, felling trees and bucking logs into manageable pieces for winter warmth. But that morning, it sputtered, coughed, and refused to roar to life with its usual gusto. It was a stark reminder that even the best tools need TLC and, sometimes, expert intervention. That experience, like many others in my years wrestling timber, taught me invaluable lessons about chainsaw maintenance, troubleshooting, and the strategic approach needed for efficient firewood preparation. This article is born from those lessons, offering you expert fixes and strategic insights to keep your Husqvarna 266 running strong and your firewood pile growing steadily.

Diagnosing and Conquering Common Husqvarna 266 Issues

The Husqvarna 266 is a workhorse, no doubt. But even the toughest horses need care. Here’s a breakdown of common problems and how to tackle them:

The Stubborn Start: Fuel, Spark, and Compression

• The Fuel System Fiasco:

  • The Culprit: Old fuel is the number one offender. Gasoline degrades over time, especially when mixed with oil. This leads to varnish buildup in the carburetor and fuel lines. I’ve seen it countless times – a perfectly good saw rendered useless by stale fuel.
  • The Fix: Always use fresh fuel! Mix fuel and oil in the correct ratio (typically 50:1 for the 266 – always check your manual!). If the saw has been sitting, drain the old fuel and replace it with fresh. Clean or replace the fuel filter, usually located inside the fuel tank.
  • Carburetor Cleaning: This is often necessary. Carefully remove the carburetor (take pictures as you disassemble!), soak it in carburetor cleaner, and use compressed air to clear any blockages. Pay special attention to the jets. Reassemble meticulously.
  • Fuel Line Inspection: Check for cracks or brittleness. Replace any suspect lines.
  • Data Point: A study by the Outdoor Power Equipment Institute (OPEI) found that over 70% of small engine problems are fuel-related.

  • The Spark Plug Saga:

  • The Culprit: A fouled spark plug can prevent the engine from firing. Carbon buildup or damage can disrupt the spark.
  • The Fix: Remove the spark plug and inspect it. A healthy plug will be clean and dry, with a tan-colored insulator. Clean a fouled plug with a wire brush or replace it. Ensure the spark plug gap is correct (refer to your manual – usually around 0.020″ – 0.025″).
  • Spark Test: With the plug removed and connected to the spark plug wire, ground the plug against the engine cylinder and pull the starter cord. You should see a strong, blue spark. If not, the ignition coil or wiring may be faulty.
  • Personal Story: I once spent an entire afternoon troubleshooting a “dead” 266, only to discover a hairline crack in the spark plug insulator. A $5 replacement solved the problem!

  • Compression Conundrums:

  • The Culprit: Low compression means the engine isn’t sealing properly, preventing it from starting. This can be caused by worn piston rings, a damaged cylinder, or a leaky head gasket.

  • The Fix: This is where things get more complex. A compression test will tell you if compression is within acceptable limits (typically 120-150 PSI for a 266). If compression is low, further investigation is needed.
  • Visual Inspection: Remove the muffler and spark plug and inspect the piston and cylinder for scoring or damage.
  • Professional Help: If you suspect compression issues, it’s often best to consult a qualified chainsaw mechanic. Engine rebuilds require specialized tools and knowledge.
  • Expert Quote: “Compression is the heart of a two-stroke engine,” says veteran chainsaw mechanic, Jim Henderson. “Without it, you’re dead in the water.”

Chainsaw Chain and Bar Issues: Keeping the Cut Sharp

• Dull Chain Blues:

  • The Culprit: A dull chain is the most common cause of poor cutting performance. It requires more effort, increases fuel consumption, and can be dangerous.
  • The Fix: Sharpen the chain regularly using a chainsaw file or a chain grinder. Maintain the correct filing angles and depth gauges.
  • Filing Technique: Use a round file of the correct diameter for your chain (usually 5/32″ or 3/16″). File each cutter consistently, maintaining the original angles. Lower the depth gauges every few sharpenings.
  • Chain Grinder: A chain grinder provides more precise and consistent sharpening. Invest in a good quality grinder if you do a lot of cutting.
  • Data Point: Studies show that a properly sharpened chain can increase cutting speed by up to 50% and reduce fuel consumption by 20%.

  • Bar Woes:

  • The Culprit: A worn or damaged bar can cause chain slippage, uneven cutting, and premature chain wear.

  • The Fix: Inspect the bar regularly for wear, burrs, and damage. Dress the bar with a bar dressing tool to remove burrs and restore the groove.
  • Bar Flipping: Flip the bar periodically to even out wear.
  • Bar Replacement: Replace the bar when it becomes excessively worn or damaged.
  • Chain Tension: Maintain proper chain tension. A loose chain can derail and cause damage. A tight chain can overheat and wear prematurely.
  • Lubrication is Key: Always use bar and chain oil. Ensure the oiler is working properly. A dry chain will wear out quickly.
  • Idiom: “An ounce of prevention is worth a pound of cure.” Regular bar and chain maintenance will save you time and money in the long run.

Vibration and Ergonomics: Reducing Fatigue and Risk

• Vibration Vibration Vibration:

  • The Culprit: Excessive vibration can lead to fatigue, numbness, and even long-term health problems like vibration white finger (VWF).
  • The Fix: Ensure the chainsaw’s anti-vibration system is working properly. Replace any worn or damaged rubber mounts.
  • Proper Technique: Use proper cutting techniques to minimize vibration. Avoid forcing the saw. Let the chain do the work.
  • Gloves: Wear anti-vibration gloves.
  • Work Breaks: Take frequent breaks to reduce fatigue.
  • Personal Experience: I learned the hard way about the importance of anti-vibration measures. After a long day of cutting without proper gloves, my hands were numb for days. Now, I always prioritize safety and ergonomics.

  • Ergonomic Considerations:

  • Posture: Maintain good posture while cutting. Avoid bending or twisting excessively.
  • Grip: Use a firm but relaxed grip.
  • Balance: Maintain a stable stance.
  • Lifting: Lift logs properly, using your legs and not your back.
  • Tool Weight: The Husqvarna 266 is a relatively heavy saw. Consider using a lighter saw for smaller tasks.

Strategic Firewood Preparation: From Forest to Fireplace

Beyond chainsaw maintenance, strategic planning is crucial for efficient firewood preparation.

Sustainable Harvesting: Respecting the Resource

• Selective Cutting:

  • The Principle: Selective cutting involves removing only specific trees, leaving the remaining forest intact. This promotes biodiversity, reduces erosion, and ensures long-term forest health.
  • Implementation: Identify mature, diseased, or damaged trees for removal. Leave healthy, young trees to grow.
  • Local Regulations: Be aware of local harvesting regulations and obtain any necessary permits.
  • Ethical Considerations: Respect the forest ecosystem. Minimize disturbance to wildlife and other vegetation.
  • Data Point: Studies by the Forest Stewardship Council (FSC) show that sustainable forestry practices can increase long-term timber yields by up to 20%.

  • Tree Species Selection:

  • Hardwoods vs. Softwoods: Hardwoods (oak, maple, beech) burn hotter and longer than softwoods (pine, fir, spruce).
  • Drying Time: Hardwoods take longer to dry than softwoods.
  • Resin Content: Softwoods tend to have higher resin content, which can lead to creosote buildup in chimneys.
  • Personal Preference: I prefer a mix of hardwoods and softwoods. Hardwoods provide the bulk of the heat, while softwoods are easier to start and burn quickly.

  • Minimizing Waste:

  • Efficient Bucking: Cut logs into lengths that are optimal for splitting and burning.

  • Utilizing Small Branches: Use small branches for kindling.
  • Composting: Compost any remaining wood scraps.
  • Wood Chips: Use wood chips for mulch or landscaping.

Workflow Optimization: Streamlining the Process

• Harvest Schedule:

  • Timing is Everything: Harvest wood in the late winter or early spring, before the sap starts to rise. This allows the wood to dry more quickly.
  • Weather Considerations: Avoid harvesting during periods of heavy rain or snow.
  • Seasonal Planning: Plan your harvest schedule well in advance.

  • Log Handling Efficiency:

  • Equipment: Use appropriate equipment for moving logs, such as log tongs, cant hooks, and skidding winches.

  • Ergonomics: Use proper lifting techniques to avoid back injuries.
  • Strategic Placement: Place logs in a convenient location for splitting and stacking.
  • Case Study: A small-scale firewood producer in Vermont increased their production by 30% by investing in a log splitter and streamlining their log handling process.

  • Splitting Strategies:

  • Manual Splitting: Use a splitting axe or maul. Choose the right tool for the job. A splitting axe is better for straight-grained wood, while a maul is better for knotty wood.

  • Hydraulic Splitters: Hydraulic splitters are faster and easier to use than manual splitting tools. Choose a splitter with sufficient tonnage for the size of logs you are splitting.
  • Splitting Wedges: Use splitting wedges to split particularly tough logs.
  • Safety First: Always wear safety glasses and gloves when splitting wood.
  • Expert Quote: “A good splitting axe is an extension of your arm,” says seasoned firewood cutter, Sarah Miller. “Choose one that feels comfortable and balanced.”

Drying Methods: Achieving Optimal Moisture Levels

• The Importance of Drying:

  • Efficient Burning: Dry wood burns more efficiently and produces more heat.
  • Reduced Creosote: Dry wood produces less creosote, reducing the risk of chimney fires.
  • Ease of Ignition: Dry wood is easier to ignite.
  • Moisture Content Targets: Aim for a moisture content of 20% or less for optimal burning.

  • Air Drying:

  • The Most Common Method: Air drying involves stacking wood in a well-ventilated location and allowing it to dry naturally.

  • Stacking Technique: Stack wood in rows, with gaps between the rows to allow for air circulation. Elevate the wood off the ground to prevent moisture absorption.
  • Sunlight: Expose the wood to sunlight to speed up the drying process.
  • Covering: Cover the top of the woodpile to protect it from rain and snow.
  • Timeframe: Air drying typically takes 6-12 months, depending on the climate and the type of wood.
  • Data Point: Research shows that properly stacked firewood dries 2-3 times faster than unstacked wood.

  • Kiln Drying:

  • Faster Drying: Kiln drying involves using a controlled environment to dry wood more quickly.
  • Commercial Operations: Kiln drying is typically used by commercial firewood producers.
  • Cost: Kiln drying is more expensive than air drying.

  • Measuring Moisture Content:

  • Moisture Meter: Use a moisture meter to measure the moisture content of the wood. Insert the probes into the center of a split piece of wood.

  • Visual Inspection: Dry wood will be lighter in weight and will have cracks on the ends.
  • Sound: Dry wood will produce a hollow sound when struck.
