7 Tips for Vintage McCulloch Chainsaw Revival

Now, let’s get into the nitty-gritty of restoring a vintage McCulloch chainsaw. These seven tips are based on my own experiences and will guide you through the process:

• Visual Inspection: Carefully examine the entire chainsaw, looking for signs of damage, wear, and corrosion. Pay close attention to the following:
  • Cylinder and Piston: Check for scoring or damage through the exhaust port. Remove the muffler for a better view.
  • Fuel Lines: Inspect for cracks, leaks, or deterioration.
  • Carburetor: Look for dirt, debris, and signs of fuel leakage.
  • Ignition System: Check the spark plug wire, coil, and points (if applicable).
  • Chain and Bar: Inspect for wear, damage, and proper tension.
  • Oil Pump: Check for leaks and proper function.
  • Recoil Starter: Inspect the rope, spring, and pawls.
  • AV (Anti-Vibration) Mounts: Check for deterioration or damage. These are often made of rubber and can degrade over time.
• Compression Test: A compression test is crucial for assessing the engine’s health. Use a compression tester to measure the cylinder pressure. A healthy engine should have a compression reading of at least 100 PSI. Anything below that indicates potential problems, such as worn piston rings or cylinder damage. I once worked on a McCulloch 10-10 that had only 60 PSI of compression. After replacing the piston rings, the compression jumped to 120 PSI, and the saw ran like new.
• Spark Test: Remove the spark plug and connect it to the spark plug wire. Ground the plug against the engine and pull the starter rope. You should see a strong, blue spark. A weak or nonexistent spark indicates a problem with the ignition system.
• Parts Availability: Before investing too much time and effort, research the availability of replacement parts. Some parts for vintage McCulloch chainsaws can be difficult to find. Online resources like eBay, chainsaw forums, and specialized parts suppliers are your best bet.
• Case Study: I recall finding a McCulloch Eager Beaver at a garage sale for $20. It looked rough, but the compression was good. However, the fuel lines were completely rotted. After replacing the fuel lines and cleaning the carburetor, the saw fired right up. This highlights the importance of a thorough inspection, as seemingly minor issues can often be easily resolved.

Tip 2: Cleaning and Disassembly

Once you’ve assessed the chainsaw’s condition, it’s time to clean and disassemble it. This will allow you to thoroughly inspect individual components and identify any hidden problems.

• External Cleaning: Start by cleaning the exterior of the chainsaw with a degreaser and a brush. Remove any dirt, grime, and old oil. A pressure washer can be helpful for removing stubborn deposits, but be careful not to damage any delicate parts.
• Disassembly: Disassemble the chainsaw carefully, following a service manual or online resources. Take photos or make notes as you go, so you can remember how everything goes back together.
• Carburetor Cleaning: The carburetor is a critical component, and it’s often the source of problems in vintage chainsaws. Disassemble the carburetor and clean all the parts with carburetor cleaner. Pay close attention to the jets and passages, making sure they are clear of debris. I’ve found that using a small wire or a guitar string can be helpful for clearing clogged jets.
• Fuel Tank Cleaning: Clean the fuel tank thoroughly to remove any old fuel, dirt, and debris. Use a fuel tank cleaner or a mixture of gasoline and degreaser. Rinse the tank thoroughly and allow it to dry completely before reassembling.
• Case Study: I was restoring a McCulloch Power Mac 6, and the carburetor was completely gummed up with old fuel. I soaked the carburetor parts in carburetor cleaner overnight and then carefully cleaned each part with a small brush and compressed air. After reassembling the carburetor, the saw ran perfectly.

Tip 3: Parts Replacement and Repair

After cleaning and disassembling the chainsaw, you’ll likely need to replace some worn or damaged parts.

• Common Replacement Parts: Some of the most common replacement parts for vintage McCulloch chainsaws include:
  • Fuel Lines: Fuel lines tend to dry out and crack over time. Replace them with new fuel lines of the correct size and material. I prefer using Tygon fuel lines, as they are resistant to fuel and oil.
  • Fuel Filter: The fuel filter prevents dirt and debris from entering the carburetor. Replace it regularly to ensure proper fuel flow.
  • Spark Plug: Replace the spark plug with a new one of the correct type. Consult the chainsaw’s manual or online resources for the correct spark plug specification.
  • Air Filter: The air filter prevents dirt and debris from entering the engine. Clean or replace it regularly to maintain proper airflow.
  • Piston Rings: If the compression is low, the piston rings may be worn. Replacing the piston rings can often restore compression and improve engine performance.
  • Carburetor Rebuild Kit: A carburetor rebuild kit includes all the necessary gaskets, diaphragms, and O-rings to rebuild the carburetor. This is a good option if the carburetor is leaking or not functioning properly.
  • Ignition Coil: If the spark is weak or nonexistent, the ignition coil may be faulty. Replacing the ignition coil can often restore spark.
• Finding Replacement Parts: Finding replacement parts for vintage McCulloch chainsaws can be challenging, but not impossible. Here are some resources:
  • eBay: eBay is a great source for used and new-old-stock (NOS) parts.
  • Chainsaw Forums: Chainsaw forums are a valuable resource for finding parts and getting advice from other enthusiasts.
  • Specialized Parts Suppliers: Several specialized parts suppliers cater to vintage chainsaw owners. These suppliers often have a wide selection of parts and can provide expert advice.
• Repairing Damaged Parts: In some cases, it may be possible to repair damaged parts instead of replacing them. For example, you can often repair a cracked fuel tank with epoxy. You can also repair damaged threads with a thread repair kit.
• Case Study: I was restoring a McCulloch 10-10, and the fuel tank had a large crack in it. I cleaned the crack thoroughly and then applied a two-part epoxy specifically designed for fuel tanks. After the epoxy cured, the fuel tank was as good as new.

Tip 4: Carburetor Adjustment

Proper carburetor adjustment is essential for ensuring that the chainsaw runs smoothly and efficiently.

• Carburetor Basics: The carburetor mixes air and fuel in the correct proportions to create a combustible mixture. Most vintage McCulloch chainsaws have a carburetor with two or three adjustment screws:
  • High-Speed (H) Screw: Controls the fuel mixture at high engine speeds.
  • Low-Speed (L) Screw: Controls the fuel mixture at low engine speeds and idle.
  • Idle Speed (T) Screw: Controls the engine’s idle speed.
• Initial Settings: Before starting the chainsaw, set the H and L screws to their initial settings. Consult the chainsaw’s manual or online resources for the correct initial settings. A common starting point is 1 to 1.5 turns out from fully closed.
• Starting the Chainsaw: Start the chainsaw and allow it to warm up for a few minutes.
• Adjusting the Low-Speed (L) Screw: Adjust the L screw until the engine idles smoothly without stalling. If the engine idles too fast, turn the L screw clockwise. If the engine stalls or hesitates when you give it throttle, turn the L screw counterclockwise.
• Adjusting the High-Speed (H) Screw: Adjust the H screw while the engine is running at full throttle. The goal is to find the leanest setting that still allows the engine to run smoothly without bogging down. If the engine bogs down or sounds like it’s struggling, turn the H screw counterclockwise. If the engine runs smoothly but sounds like it’s running too lean (a high-pitched whine), turn the H screw clockwise.
• Adjusting the Idle Speed (T) Screw: Adjust the T screw until the engine idles at the correct speed. Consult the chainsaw’s manual or online resources for the correct idle speed.
• Fine-Tuning: After making the initial adjustments, fine-tune the carburetor settings to achieve optimal performance. This may require some trial and error.
• Case Study: I was having trouble getting a McCulloch Eager Beaver to run smoothly. It would idle fine, but it would bog down when I gave it throttle. After experimenting with the carburetor adjustments, I discovered that the L screw was set too lean. Turning the L screw counterclockwise a quarter of a turn made a huge difference, and the saw ran perfectly.

Tip 5: Ignition System Troubleshooting

The ignition system is responsible for creating the spark that ignites the fuel mixture. If the chainsaw is not starting or running properly, the ignition system may be the problem.

• Spark Plug Inspection: Start by inspecting the spark plug. A fouled spark plug can prevent the engine from starting. Clean the spark plug with a wire brush and check the gap. Consult the chainsaw’s manual or online resources for the correct spark plug gap.
• Spark Test: Perform a spark test to check for spark. Remove the spark plug and connect it to the spark plug wire. Ground the plug against the engine and pull the starter rope. You should see a strong, blue spark.
• Ignition Coil Testing: If there is no spark, the ignition coil may be faulty. Use a multimeter to test the ignition coil’s primary and secondary windings. Consult the chainsaw’s manual or online resources for the correct resistance values.
• Points and Condenser (If Applicable): Some vintage McCulloch chainsaws use a points and condenser ignition system. If the points are dirty or corroded, they may not be making good contact. Clean the points with a points file or sandpaper. If the condenser is faulty, it can cause a weak spark or no spark at all.
• Flywheel Key: The flywheel key is a small metal key that locates the flywheel on the crankshaft. If the flywheel key is sheared, it can cause the timing to be off, resulting in a weak spark or no spark.
• Case Study: I was working on a McCulloch Pro Mac 1010S that had no spark. I tested the ignition coil with a multimeter, and the secondary winding was open. I replaced the ignition coil, and the saw started right up.

Tip 6: Lubrication and Maintenance

Proper lubrication and maintenance are essential for extending the life of your vintage McCulloch chainsaw.

• Chain Lubrication: Keep the chain well-lubricated with chain oil. Check the oil level regularly and refill as needed. Use a high-quality chain oil specifically designed for chainsaws. I’ve found that using a bar and chain oil with a tackifier helps the oil adhere to the chain better, reducing wear and tear.
• Air Filter Cleaning: Clean the air filter regularly to maintain proper airflow. A dirty air filter can restrict airflow and cause the engine to run poorly. Wash the air filter with soap and water and allow it to dry completely before reinstalling.
• Fuel Filter Replacement: Replace the fuel filter regularly to prevent dirt and debris from entering the carburetor.
• Spark Plug Replacement: Replace the spark plug annually or as needed.
• Chain Sharpening: Keep the chain sharp to ensure efficient cutting. Use a chainsaw file or a chainsaw sharpener to sharpen the chain. I prefer using a chainsaw file, as it gives me more control over the sharpening process.
• Bar Maintenance: Keep the bar clean and free of debris. Check the bar rails for wear and damage. Dress the bar rails with a bar rail dressing tool to remove any burrs or imperfections.
• Storage: When storing the chainsaw for extended periods, drain the fuel tank and run the engine until it stalls. This will prevent the fuel from gumming up the carburetor. Store the chainsaw in a dry place. I also like to spray a fogging oil into the cylinder through the spark plug hole to prevent corrosion.
• Case Study: I had a McCulloch Mac 100 that I used for occasional trimming around my property. I neglected to clean the air filter regularly, and the engine started running poorly. After cleaning the air filter, the saw ran like new. This highlights the importance of regular maintenance.

Tip 7: Safety First!

Safety should always be your top priority when working with chainsaws.

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including:
  • Eye Protection: Safety glasses or a face shield to protect your eyes from flying debris.
  • Hearing Protection: Earplugs or earmuffs to protect your hearing from the loud noise of the chainsaw.
  • Gloves: Heavy-duty gloves to protect your hands from cuts and abrasions.
  • Chaps: Chainsaw chaps to protect your legs from accidental cuts.
  • Steel-Toed Boots: Steel-toed boots to protect your feet from falling objects.
• Safe Operating Practices: Follow these safe operating practices:
  • Read the Manual: Familiarize yourself with the chainsaw’s operating manual before using it.
  • Inspect the Chainsaw: Inspect the chainsaw before each use to ensure that it is in good working order.
  • Clear the Work Area: Clear the work area of any obstacles, such as branches, rocks, and debris.
  • Use a Firm Grip: Hold the chainsaw with a firm grip with both hands.
  • Keep Your Balance: Maintain your balance and avoid overreaching.
  • Be Aware of Kickback: Be aware of the risk of kickback, which is a sudden and violent reaction that can occur when the tip of the chainsaw bar comes into contact with a solid object.
  • Never Cut Above Shoulder Height: Never cut above shoulder height, as this increases the risk of losing control of the chainsaw.
  • Stop the Chainsaw Before Moving: Stop the chainsaw before moving from one location to another.
  • Never Use a Chainsaw When Fatigued: Never use a chainsaw when you are fatigued or under the influence of drugs or alcohol.
• First Aid: Keep a first aid kit readily available in case of an accident.
• Case Study: I once witnessed a logger who was not wearing chaps accidentally cut himself in the leg with a chainsaw. Fortunately, the cut was not too deep, but it could have been much worse. This incident reinforced the importance of wearing appropriate PPE.
