Homelite Old Chainsaw Restorations (5 Pro Tips for Revival)

Homelite Old Chainsaw Restorations: 5 Pro Tips for Revival

Homelite chainsaws, known for their robust build and simplicity, hold a special place in the hearts of many. I remember my grandfather’s Homelite, a beast of a machine that seemed to run forever. These saws, however, often end up neglected in garages and sheds. Don’t let them become forgotten relics! With a little know-how and elbow grease, you can bring these vintage powerhouses back to life.

Tip #1: The Initial Assessment – Diagnosing the Patient

Before diving into any restoration project, a thorough assessment is crucial. I always start by visually inspecting the entire saw. This process helps me identify any obvious issues and plan my approach.

• Fuel System: Check the fuel lines for cracks or deterioration. Old fuel lines often become brittle and can cause leaks, leading to poor performance or even a fire hazard. The fuel tank itself should be inspected for any signs of rust or damage.

• Carburetor: The carburetor is often the heart of the problem in older chainsaws. Look for signs of dirt, varnish, or corrosion. A gummed-up carburetor can prevent the saw from starting or running smoothly.

• Ignition System: The spark plug and ignition coil are essential for starting the engine. Remove the spark plug and inspect it for fouling or damage. A weak spark can also indicate a faulty ignition coil. I use a spark tester to properly check the spark.

• Compression: Compression is the lifeblood of any two-stroke engine. A lack of compression indicates worn piston rings or cylinder damage. I use a compression tester, aiming for at least 90 PSI on most Homelite models. Anything below that will require further investigation.

• Bar and Chain: The bar and chain are the cutting components of the saw. Check the bar for wear or damage, and ensure the chain is sharp and properly tensioned. A dull chain will make cutting difficult and put unnecessary strain on the engine.

  Tip #2: Fuel System Revival – Clearing the Blockages

  The fuel system is a common culprit in non-starting or poorly running chainsaws. Over time, old fuel can degrade and leave behind varnish and deposits that clog fuel lines, filters, and the carburetor. I’ve seen fuel systems so gummed up they looked like honey!

  • Fuel Tank Cleaning: Drain any old fuel from the tank and inspect it for debris. I use a clean cloth and a long screwdriver to remove any loose particles. For stubborn deposits, I sometimes use a fuel tank cleaner specifically designed for small engines.

  • Fuel Line Replacement: Replace all fuel lines with new ones. Old fuel lines become brittle and crack, leading to leaks and poor fuel delivery. I typically use fuel lines that are compatible with ethanol-blended fuels.

    • Measurement: I measure the old fuel lines to ensure I purchase the correct replacement size. Common sizes are 1/8″ and 3/16″ ID (Inner Diameter).

  • Fuel Filter Replacement: Replace the fuel filter with a new one. A clogged fuel filter restricts fuel flow and can cause the engine to stall.

  • Carburetor Cleaning: Disassemble the carburetor and clean all the components thoroughly. I use carburetor cleaner and small brushes to remove any varnish or deposits. Be sure to pay close attention to the jets and passages.

    • Important Note: Make sure to take pictures of the carburetor before disassembly. This will help you reassemble it correctly.
    • Ultrasonic Cleaning: For heavily soiled carburetors, I recommend using an ultrasonic cleaner. This device uses high-frequency sound waves to dislodge dirt and debris from even the most inaccessible areas.

  Takeaway: A clean and properly functioning fuel system is essential for reliable chainsaw operation. Regular maintenance and the use of fresh fuel can prevent many fuel-related problems.

  Tip #3: Ignition System Tune-Up – Sparking New Life

  A strong and consistent spark is crucial for starting the engine. Over time, the spark plug can become fouled, and the ignition coil can weaken. I always make sure to check the ignition system as part of my restoration process.

  • Spark Plug Inspection and Replacement: Remove the spark plug and inspect it for fouling, cracks, or damage. Clean the spark plug with a wire brush or replace it with a new one.

    • Spark Plug Gap: Ensure the spark plug gap is set correctly. I use a spark plug gapping tool to set the gap to the manufacturer’s specifications, typically around 0.025″ to 0.030″ for Homelite chainsaws.

  • Ignition Coil Testing: The ignition coil provides the high voltage needed to create a spark. Use a multimeter to test the coil’s resistance. If the resistance is outside the manufacturer’s specifications, the coil may need to be replaced.

    • Air Gap Adjustment: If the ignition coil is adjustable, ensure the air gap between the coil and the flywheel is set correctly. A business card is often used as a shim to set the correct gap.

  • Flywheel Inspection: Inspect the flywheel for any damage or corrosion. Clean the flywheel with a wire brush to ensure good contact with the ignition coil.

  Takeaway: A properly functioning ignition system is essential for reliable starting and smooth engine operation. Regular spark plug replacement and coil testing can prevent ignition-related problems.

  Tip #4: Compression Restoration – Rebuilding the Heart

  Low compression is a sign of worn piston rings or cylinder damage. This is a more involved repair, but it can often be tackled with some patience and the right tools. I’ve brought back many old Homelites with this method.

  • Compression Testing: Use a compression tester to measure the engine’s compression. As mentioned earlier, aim for at least 90 PSI on most Homelite models.

  • Cylinder Inspection: Remove the cylinder head and inspect the cylinder walls for scoring or damage. Light scoring can sometimes be cleaned up with a honing tool.

  • Piston and Ring Inspection: Remove the piston and inspect the piston rings for wear or damage. If the rings are worn, replace them with new ones.

    • Ring End Gap: When installing new piston rings, ensure the ring end gap is within the manufacturer’s specifications.

  • Cylinder Honing: If the cylinder walls are lightly scored, use a honing tool to smooth them out. This will improve the seal between the piston rings and the cylinder walls.

  • Reassembly: Reassemble the engine, using new gaskets and seals as needed. Ensure all bolts are tightened to the correct torque specifications.

    • Torque Wrench: A torque wrench is essential for ensuring proper bolt tightening.

  Case Study: I once restored a Homelite Super XL that had sat neglected for over 20 years. The compression was a dismal 60 PSI. After replacing the piston rings and honing the cylinder, the compression jumped to 120 PSI, and the saw ran like new!

  Takeaway: Restoring compression can significantly improve engine performance and extend the life of your chainsaw. While it’s a more complex repair, it’s often worth the effort.

  Tip #5: Bar and Chain Maintenance – Sharpening the Edge

  A sharp chain and a well-maintained bar are crucial for efficient and safe cutting. I always pay close attention to the bar and chain as part of my chainsaw restoration.

  • Chain Sharpening: Sharpen the chain regularly using a chainsaw file or a chain grinder. A sharp chain will cut faster and more efficiently, reducing strain on the engine.

    • Filing Angle: Maintain the correct filing angle when sharpening the chain. This will ensure the chain cuts properly and efficiently.

  • Bar Inspection and Maintenance: Inspect the bar for wear or damage. Clean the bar groove regularly to remove sawdust and debris.

    • Bar Dressing: Use a bar dressing tool to remove any burrs or sharp edges from the bar. This will prevent the chain from binding and improve cutting performance.

  • Chain Tensioning: Adjust the chain tension regularly to ensure it is neither too tight nor too loose. A properly tensioned chain will cut smoothly and safely.

    • Tensioning Procedure: The chain should be able to be pulled away from the bar slightly, but not so much that it sags.

  • Chain Lubrication: Ensure the chain is properly lubricated. A lack of lubrication can cause the chain to overheat and wear prematurely.

    • Oil Type: Use a high-quality bar and chain oil specifically designed for chainsaws.

  Takeaway: A sharp chain and a well-maintained bar are essential for safe and efficient cutting. Regular maintenance and proper lubrication will extend the life of your bar and chain.
