Stihl 064 For Sale (5 Proven Tips To Spot Quality Chainsaws)

Why did the chainsaw break up with the log? Because it said, “I’m tired of being used!”

Alright folks, let’s talk chainsaws, specifically the legendary Stihl 064. Finding a good used one is like finding a needle in a haystack, but it’s a needle worth searching for. I’ve spent years in the woods, felling trees, processing firewood, and generally putting chainsaws through their paces. I’ve seen good saws go bad and bad saws… well, they never really go anywhere good. This guide is born from that experience. I’m going to share my hard-earned knowledge to help you spot a quality used Stihl 064 and avoid getting stuck with a lemon. We’ll delve into the technical nitty-gritty, from engine compression to bar alignment, so you can make an informed decision and get the most bang for your buck.

The Allure of the Stihl 064: A Logger’s Love Affair

The Stihl 064. Just the name evokes images of raw power and relentless performance. For many professional loggers and serious firewood cutters, it’s the gold standard. What makes it so special? It’s a combination of factors: a powerful engine, robust construction, and a reputation for reliability that’s been forged over decades.

I remember one particularly brutal winter in the Adirondacks. We were facing a firewood shortage, and the only trees accessible were massive, frozen hardwoods. My little homeowner-grade saw was struggling. A seasoned logger I knew offered me his 064 for a few days. The difference was night and day. It chewed through those frozen logs like they were butter. That experience cemented my respect for the 064 and its ability to handle tough jobs.

Why Buy Used?

Newer chainsaws are great, don’t get me wrong, but they don’t always have the same rugged simplicity as older models like the 064. Plus, a well-maintained used 064 can offer comparable performance at a significantly lower price. The key is knowing what to look for. This guide focuses on the Stihl 064 because of its enduring popularity and availability in the used market.

5 Proven Tips to Spot Quality Chainsaws

Here are my tried-and-true tips, gleaned from years of experience, to help you identify a solid Stihl 064 in the used market. We’ll go beyond just a visual inspection and dive into the technical details.

1. Compression: The Heart of the Matter

Compression is the single most important factor in determining the health of a chainsaw engine. Low compression means a weak engine, poor performance, and potentially expensive repairs down the line.

How to Test Compression:

The Pull Test (Quick and Dirty): This is a basic test you can do without any tools. With the chainsaw off and the chain brake engaged, slowly pull the starter cord. You should feel strong resistance and a distinct “bounce back” as the piston reaches the top of its stroke. Weak resistance or a smooth, easy pull indicates low compression.
The Compression Tester (The Definitive Test): This is the most accurate method. You’ll need a compression tester, which can be purchased at most auto parts stores or online.
1. Remove the spark plug.
2. Screw the compression tester into the spark plug hole.
3. Engage the chain brake.
4. Pull the starter cord rapidly several times until the needle on the tester stops rising.

Acceptable Compression Readings:

A healthy Stihl 064 should have a compression reading of 130 PSI (pounds per square inch) or higher. Anything below 110 PSI is a red flag. Between 110 and 130 PSI, the saw might run, but it’s likely nearing the end of its life and will require a rebuild soon.

Technical Insight: Compression is a measure of the pressure created inside the cylinder when the piston moves upwards. This pressure is essential for igniting the fuel-air mixture and generating power. Loss of compression can be caused by worn piston rings, cylinder damage, or leaky valves (though less common in two-stroke engines like the 064).

Personal Story: I once bought a used chainsaw that “ran great,” according to the seller. I did the pull test, and it felt okay, but I didn’t have a compression tester with me. Big mistake! After a few hours of cutting, the saw started losing power and eventually died. A compression test revealed a dismal 90 PSI. I ended up spending more on a rebuild than I would have on a better saw in the first place. Lesson learned: always check the compression!

2. Visual Inspection: Scars Tell Stories

A thorough visual inspection can reveal a lot about how well the chainsaw has been maintained and the type of use it has endured.

Key Areas to Examine:

Cylinder Fins: Check for broken or damaged cylinder fins. These fins are crucial for dissipating heat. Damaged fins can lead to overheating and engine damage.
Air Filter: A dirty or damaged air filter is a sign of neglect. It can also indicate that the engine has been running with insufficient air, leading to premature wear. The air filter should be clean and properly seated.
Fuel Lines and Filter: Inspect the fuel lines for cracks, leaks, or stiffness. Replace them if they are in poor condition. Check the fuel filter inside the fuel tank for debris. A clogged fuel filter can starve the engine of fuel.
Spark Plug: Examine the spark plug for its condition. A black, sooty spark plug indicates a rich fuel mixture. A white, ashy spark plug indicates a lean fuel mixture. The spark plug should be clean and have a light tan color.
Bar and Chain: Check the bar for wear, damage, and straightness. Make sure the chain is sharp and properly tensioned. Look for signs of excessive wear on the chain drive sprocket.
AV (Anti-Vibration) Mounts: These rubber mounts isolate the engine from the handles, reducing vibration. Check them for cracks or damage. Worn AV mounts can make the saw uncomfortable to use and can also indicate that the saw has been subjected to excessive vibration.
Overall Cleanliness: A clean chainsaw is usually a sign that the owner takes pride in their equipment and has likely maintained it well. A chainsaw caked in dirt and grime might have been neglected.

Technical Insight: The Stihl 064, like many chainsaws, uses a two-stroke engine. Two-stroke engines require a mixture of oil and gasoline for lubrication. Running a two-stroke engine with insufficient oil can cause severe damage, including piston seizure.

Data Point: A study by the US Forest Service found that chainsaws with regularly cleaned air filters had a 20% longer lifespan than those with neglected air filters.

3. Starting and Idling: Listen Closely

How a chainsaw starts and idles can tell you a lot about its overall condition and carburetor adjustment.

Starting Procedure:

Follow the manufacturer’s recommended starting procedure. For the Stihl 064, this typically involves engaging the chain brake, setting the choke, and pulling the starter cord until the engine “pops” or briefly fires. Then, disengage the choke and pull the cord again to start the engine.
A healthy Stihl 064 should start within a few pulls when cold and on the first pull when warm. Excessive pulling or difficulty starting can indicate a problem with the carburetor, ignition system, or compression.

Idling Behavior:

Once the engine is running, let it idle for a few minutes. The engine should idle smoothly and consistently without stalling or sputtering.
Pay attention to the idle speed. It should be low enough that the chain does not move but high enough to prevent the engine from stalling.
Listen for any unusual noises, such as rattling, knocking, or hissing. These noises can indicate internal engine damage.

Carburetor Adjustment:

The carburetor controls the air-fuel mixture. An improperly adjusted carburetor can cause various problems, including poor starting, rough idling, and reduced power.
The Stihl 064 carburetor typically has three adjustment screws: a low-speed (L) screw, a high-speed (H) screw, and an idle speed (LA) screw.
Adjusting the carburetor requires a special tool and some experience. If you’re not comfortable doing it yourself, it’s best to take the chainsaw to a qualified technician.

Technical Insight: Carburetor adjustment is crucial for optimal engine performance and fuel efficiency. A lean fuel mixture (too much air) can cause the engine to overheat and damage the piston. A rich fuel mixture (too much fuel) can cause the engine to run poorly and foul the spark plug.

Case Study: In one of my firewood processing projects, I had a Stihl 064 that was running poorly. It was difficult to start, idled roughly, and lacked power. I initially suspected a compression issue, but the compression test came back within acceptable limits. After some troubleshooting, I discovered that the carburetor was severely out of adjustment. I carefully adjusted the carburetor using the manufacturer’s specifications, and the saw ran like new.

4. Cutting Performance: Put It to the Test (Safely!)

The ultimate test of a chainsaw is its cutting performance. If possible, ask the seller if you can test the chainsaw on a log.

Safety First:

Always wear appropriate safety gear, including a helmet, eye protection, hearing protection, gloves, and chainsaw chaps.
Make sure the chain is sharp and properly tensioned.
Clear the area of any obstacles and bystanders.
Use proper cutting techniques.

Cutting Test:

Start the chainsaw and let it warm up for a few minutes.
Make a few cuts through a log of moderate size (around 12-16 inches in diameter).
Pay attention to the following:
- Power: The chainsaw should have plenty of power to cut through the log without bogging down.
- Chain Speed: The chain should move smoothly and quickly through the wood.
- Vibration: Excessive vibration can indicate a problem with the engine, bar, or chain.
- Smoke: Excessive smoke can indicate a problem with the fuel mixture or engine lubrication.

Technical Insight: The cutting performance of a chainsaw is affected by several factors, including engine power, chain sharpness, chain speed, and bar length. A dull chain can significantly reduce cutting performance and increase the risk of kickback.

Best Practice: When testing a chainsaw, try cutting both with the grain and against the grain. Cutting against the grain is more demanding and can reveal any weaknesses in the engine or chain.

Data Point: A study by Oregon Chain found that a sharp chain can reduce cutting time by up to 50% compared to a dull chain.

5. Paper Trail: Service Records and Ownership

While not always available, any documentation about the chainsaw’s history can be invaluable.

Look for:

Original Purchase Receipt: This can verify the age of the chainsaw and the seller’s ownership.
Service Records: These records can show that the chainsaw has been regularly maintained and repaired.
Owner’s Manual: The owner’s manual contains important information about the chainsaw’s operation, maintenance, and safety.
Warranty Information: While the original warranty may have expired, it can still provide some insight into the chainsaw’s history.

Technical Insight: Regular maintenance, such as air filter cleaning, spark plug replacement, and carburetor adjustment, can significantly extend the life of a chainsaw.

Personal Experience: I once bought a used Stihl 064 from a logger who had meticulously kept service records. The records showed that the chainsaw had been regularly serviced by a qualified technician and that all necessary repairs had been made promptly. The chainsaw was in excellent condition and ran flawlessly for years.

Red Flags:

A seller who is unwilling to provide any information about the chainsaw’s history.
Missing or incomplete service records.
Signs of tampering or modifications.
