A Closer Look at the Engine

The heart of the Stihl 036 is its 61.5 cc two-stroke engine. This engine is known for its robust design and strong power output. The two-stroke design means that the engine completes a power cycle with every revolution of the crankshaft, resulting in a high power-to-weight ratio. The engine features a chrome-plated cylinder for increased durability and resistance to wear.

Fuel and Oil Mix: Like all two-stroke engines, the Stihl 036 requires a fuel and oil mixture. The recommended ratio is 50:1 (50 parts gasoline to 1 part two-stroke oil). Always use high-quality two-stroke oil specifically designed for air-cooled engines. Using the wrong type of oil or an incorrect mixture can lead to engine damage and premature wear.

Carburetor: The carburetor is responsible for mixing the fuel and air in the correct proportions. The Stihl 036 uses a Walbro carburetor, which is known for its reliability and ease of adjustment. The carburetor has three main adjustment screws:

• L (Low Speed): Adjusts the fuel mixture at idle and low speeds.
• H (High Speed): Adjusts the fuel mixture at high speeds.
• LA (Idle Speed): Adjusts the engine’s idle speed.

Proper carburetor adjustment is crucial for optimal engine performance and fuel efficiency.

Guide Bar and Chain Selection

Choosing the right guide bar and chain is essential for maximizing the performance and safety of your Stihl 036. The available bar lengths range from 16″ to 25″, but the optimal length will depend on the size of the wood you’re cutting.

5 Expert Tips for Vintage Chainsaws Like the Stihl 036

Now, let’s get to the heart of the matter: how to keep your vintage Stihl 036 running strong for years to come. These tips are based on my years of experience working with these saws and are designed to help you get the most out of your investment.

Tip #1: Master the Art of Carburetor Tuning

One of the most crucial aspects of maintaining a vintage chainsaw is understanding and mastering carburetor tuning. A properly tuned carburetor ensures that the engine receives the correct fuel-air mixture, which is essential for optimal performance, fuel efficiency, and engine longevity.

Symptoms of a Poorly Tuned Carburetor:

• Hard Starting: The engine is difficult to start, especially when cold.
• Rough Idle: The engine idles unevenly or stalls frequently.
• Poor Acceleration: The engine hesitates or bogs down when you try to accelerate.
• Excessive Smoke: The engine produces excessive smoke, indicating a rich fuel mixture.
• Overheating: The engine runs hot, which can lead to engine damage.

The Carburetor Tuning Process:

1. Warm Up the Engine: Start the engine and let it run for a few minutes to warm up to operating temperature.
2. Locate the Adjustment Screws: The L (Low Speed), H (High Speed), and LA (Idle Speed) screws are typically located on the side of the carburetor.
3. Adjust the Idle Speed (LA): Turn the LA screw until the engine idles smoothly without the chain moving.
4. Adjust the Low-Speed Mixture (L): Slowly turn the L screw clockwise (leaner) or counterclockwise (richer) until the engine idles smoothly and responds quickly to throttle inputs. A lean mixture will cause the engine to rev up quickly and then die, while a rich mixture will cause the engine to bog down.
5. Adjust the High-Speed Mixture (H): This is the most critical adjustment. With the engine running at full throttle, slowly turn the H screw clockwise (leaner) until the engine starts to sound “thin” or “screaming.” Then, slowly turn the H screw counterclockwise (richer) until the engine runs smoothly and powerfully without bogging down. Important: Running the engine too lean at high speed can cause severe engine damage.
6. Fine-Tune: After making these adjustments, recheck the idle speed and low-speed mixture and make any necessary fine-tuning adjustments.

Tools You’ll Need:

• Screwdriver: A small flathead screwdriver is required to adjust the carburetor screws.
• Tachometer (Optional): A tachometer can be used to monitor the engine’s RPM, which can help you fine-tune the high-speed mixture.

My Personal Experience: I’ve found that the Stihl 036 is particularly sensitive to carburetor adjustments. Even a slight change in the mixture can have a significant impact on performance. It’s worth taking the time to experiment and find the sweet spot where the engine runs smoothly and powerfully.

Caution: If you’re not comfortable tuning the carburetor yourself, it’s best to take the saw to a qualified mechanic.

Tip #2: Regular Maintenance is Key

Vintage chainsaws require more frequent maintenance than modern models. Regular maintenance will not only keep your saw running smoothly but will also extend its lifespan.

Essential Maintenance Tasks:

• Air Filter Cleaning: Clean the air filter after every use. A dirty air filter restricts airflow to the engine, leading to reduced power and increased fuel consumption. Use compressed air or warm, soapy water to clean the filter.
• Spark Plug Inspection and Cleaning: Inspect the spark plug regularly and clean or replace it as needed. A fouled spark plug can cause hard starting and poor performance. The recommended spark plug gap for the Stihl 036 is 0.5 mm (0.020″).
• Fuel Filter Replacement: Replace the fuel filter every year or more frequently if you notice a decrease in performance. A clogged fuel filter restricts fuel flow to the carburetor.
• Chain Sharpening: Keep the chain sharp. A dull chain is not only less efficient but also more dangerous. Use a chainsaw file and a guide to sharpen the chain at the correct angle.
• Bar Maintenance: Clean the guide bar regularly and check for wear. Remove any burrs or damage with a file. Ensure that the oiler hole is clear.
• Chain Oiler Adjustment: Check the chain oiler to ensure that it’s delivering enough oil to the chain. Adjust the oiler if necessary. Insufficient oil can lead to premature wear of the chain and bar.
• Cooling Fins Cleaning: Keep the cooling fins on the cylinder clean. Overheating can cause severe engine damage.
• Inspect Fuel Lines and Seals: Regularly inspect fuel lines and seals for cracks or leaks. Replace them as needed.

Maintenance Schedule:

• Daily: Air filter cleaning, chain sharpening, bar maintenance, chain oiler check.
• Weekly: Spark plug inspection, fuel filter check.
• Annually: Fuel filter replacement, spark plug replacement, thorough inspection of all components.

Personal Story: I once neglected to clean the air filter on my 036 for too long. The saw started running poorly, and I eventually had to replace the piston and cylinder. That experience taught me the importance of regular maintenance.

Tip #3: Use High-Quality Fuel and Oil

The quality of the fuel and oil you use can have a significant impact on the performance and longevity of your Stihl 036. Always use high-quality gasoline with an octane rating of 89 or higher. Avoid using ethanol-blended fuels, as ethanol can damage the fuel system components. If you must use ethanol-blended fuel, make sure it’s no more than 10% ethanol (E10).

Two-Stroke Oil: Use high-quality two-stroke oil specifically designed for air-cooled engines. Synthetic oils offer superior lubrication and protection compared to conventional oils. The recommended fuel-oil ratio for the Stihl 036 is 50:1.

Fuel Stabilizer: If you’re not going to use your chainsaw for an extended period, add a fuel stabilizer to the fuel tank. Fuel stabilizer prevents the fuel from breaking down and forming deposits in the carburetor.

Why Quality Matters:

• Prevents Engine Damage: High-quality fuel and oil provide better lubrication and cooling, reducing the risk of engine damage.
• Improves Performance: Clean fuel and proper lubrication ensure optimal engine performance and fuel efficiency.
• Extends Engine Life: Using quality fuel and oil can significantly extend the life of your chainsaw.

Data Insight: In my experience, using premium synthetic two-stroke oil has resulted in noticeably cleaner engine components and reduced carbon buildup compared to using conventional oil.

Tip #4: Master Safe Felling Techniques

Felling trees is one of the most dangerous aspects of wood processing. It’s essential to master safe felling techniques to protect yourself and others.

Essential Safety Gear:

• Helmet: Protects your head from falling branches and debris.
• Eye Protection: Safety glasses or a face shield protect your eyes from flying chips and debris.
• Hearing Protection: Earplugs or earmuffs protect your hearing from the loud noise of the chainsaw.
• Gloves: Protect your hands and improve your grip.
• Chainsaw Chaps: Protect your legs from chainsaw cuts.
• Steel-Toed Boots: Protect your feet from falling logs and other hazards.

Felling Techniques:

1. Assess the Tree: Before felling a tree, assess its size, lean, and any potential hazards, such as dead branches or power lines.
2. Plan Your Escape Route: Identify two clear escape routes that are at a 45-degree angle away from the direction of the fall.
3. Make the Notch: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about 1/3 of the tree’s diameter. The top cut of the notch should be at a 45-degree angle, and the bottom cut should be horizontal.
4. Make the Felling Cut: Make the felling cut on the opposite side of the notch, slightly above the horizontal cut of the notch. Leave a hinge of wood between the felling cut and the notch. The hinge controls the direction of the fall.
5. Use Wedges (If Necessary): If the tree is leaning in the wrong direction or if you’re concerned about it falling back on the saw, use felling wedges to help guide the fall.
6. Warn Others: Before making the felling cut, warn anyone nearby to stay clear.
7. Retreat Safely: After the tree starts to fall, retreat quickly and safely along your planned escape route.

Bore Cutting: For larger trees, you may need to use a bore cut. A bore cut involves plunging the saw into the trunk to create a hinge before making the final felling cut. This technique helps to prevent the tree from splitting or kicking back.

Case Study: I was once felling a large oak tree that was leaning heavily to one side. I used felling wedges to help guide the fall, but the tree started to split as it fell. Fortunately, I had planned my escape route and was able to retreat safely. This experience reinforced the importance of always being prepared for the unexpected.

Tip #5: Proper Storage Extends Lifespan

Proper storage is crucial for preserving your Stihl 036, especially during the off-season.

Storage Procedures:

1. Drain the Fuel Tank: Drain the fuel tank completely to prevent the fuel from breaking down and forming deposits in the carburetor.
2. Run the Carburetor Dry: Start the engine and let it run until it stalls to remove any remaining fuel from the carburetor.
3. Remove the Spark Plug: Remove the spark plug and pour a small amount of two-stroke oil into the cylinder. Pull the starter cord a few times to distribute the oil throughout the cylinder. Replace the spark plug.
4. Clean the Saw: Clean the saw thoroughly, removing any sawdust, dirt, or debris.
5. Lubricate the Bar and Chain: Apply a thin coat of oil to the bar and chain to prevent rust.
6. Store in a Dry Place: Store the saw in a dry, well-ventilated place. Avoid storing it in direct sunlight or in damp conditions.

Long-Term Storage: For long-term storage (more than a few months), consider removing the bar and chain and storing them separately. This will help to prevent rust and corrosion.

Insight: Storing your chainsaw properly not only protects it from the elements but also prevents potential problems when you’re ready to use it again. I’ve seen many chainsaws ruined by improper storage.
