Stihl EZ Start Chainsaw: Benefits & Downsides (5 Tips)

Do you remember the distinct aroma of freshly cut wood, the satisfying crackle of a well-fed fire on a cold winter’s night? It’s a primal connection, a dance with nature that many of us find deeply satisfying. But let’s be honest, getting there – from standing tree to cozy hearth – often involves a chainsaw. And for many, the Stihl EZ Start system sounds like a dream come true. I know I was intrigued when I first heard about it. Is it the real deal? Are there downsides? Let’s dive in.

Stihl EZ Start Chainsaw: Benefits & Downsides (5 Tips)

The global firewood market is a surprisingly large one. A 2023 report by Global Market Insights projects the global firewood market to reach $14.5 billion by 2032. This highlights the enduring appeal of wood as a heating source, especially in rural communities and for those seeking off-grid solutions. With this demand comes the need for efficient and user-friendly tools, which is why chainsaws like those with the Stihl EZ Start system are gaining traction.

What is Stihl EZ Start?

The Stihl EZ Start system is designed to make starting a chainsaw significantly easier. Traditional chainsaws require a strong, sharp pull on the starter cord to overcome the engine’s compression. This can be difficult, especially in cold weather or for users with limited strength.

The EZ Start system incorporates a spring-assisted starting mechanism. This mechanism stores energy as you pull the cord gently, then releases that energy to spin the engine faster, requiring much less effort. Think of it like a slingshot for your engine.

Benefits of the Stihl EZ Start System

Having used chainsaws with and without the EZ Start system, I can vouch for the difference it makes. Here’s a more detailed look at the benefits:

Reduced Starting Effort: This is the primary benefit. The EZ Start system can reduce the pulling force required by up to 50%. This is a game-changer for anyone who struggles with traditional chainsaw starting, including beginners, older users, and those with shoulder or back problems. I remember one particular instance where a friend, recovering from a shoulder injury, was able to continue helping with firewood prep thanks to the EZ Start on my MS 251. Without it, he would have been sidelined.
Easier Cold Starts: Cold engines are notoriously difficult to start. The EZ Start system helps to overcome the increased resistance caused by cold oil and tighter engine tolerances. This means fewer frustrating attempts and faster start-ups, especially during those chilly autumn days when you’re trying to get a head start on your firewood supply.
Less Wear and Tear on the Starter Mechanism: Because you’re not yanking on the starter cord with all your might, there’s less stress on the starter components, potentially extending their lifespan. This can translate to fewer repairs and lower maintenance costs over the long run.
Increased User Confidence: For beginners, the fear of not being able to start the chainsaw can be a major deterrent. The EZ Start system eliminates that anxiety, allowing them to focus on learning proper cutting techniques and safety procedures. I’ve seen firsthand how a successful start on the first try can significantly boost a new user’s confidence and willingness to learn.
Ideal for Occasional Users: If you only use your chainsaw occasionally, the EZ Start system is even more valuable. You’re less likely to be “in shape” for the physical demands of starting a traditional chainsaw, making the easier start a welcome feature.

Downsides of the Stihl EZ Start System

While the EZ Start system offers significant advantages, it’s not without its drawbacks. Here are some potential downsides to consider:

Increased Complexity: The EZ Start mechanism adds complexity to the chainsaw’s engine. This means there are more parts that could potentially fail, increasing the risk of repairs. While Stihl is known for its quality, any added complexity introduces a potential point of failure.
Potential for Higher Repair Costs: If the EZ Start mechanism does break down, repairing it can be more expensive than repairing a traditional starter. This is because the EZ Start system involves specialized parts and requires a more skilled technician to diagnose and fix.
Slightly Increased Weight: The EZ Start mechanism adds a small amount of weight to the chainsaw. While the difference is usually negligible, some users may notice it, especially during extended use. For those who prioritize lightweight chainsaws, this could be a factor.
Not a Substitute for Proper Maintenance: The EZ Start system makes starting easier, but it doesn’t negate the need for proper chainsaw maintenance. You still need to clean the air filter, replace the spark plug, sharpen the chain, and use fresh fuel to ensure optimal performance. I’ve seen people assume the EZ Start means they can neglect maintenance, only to be disappointed when the saw still won’t start after a while.
Cost: Chainsaws with the EZ Start system often come with a higher price tag compared to models without it. You need to weigh the benefits of easier starting against the added cost to determine if it’s worth the investment for your specific needs.

5 Tips for Using a Stihl EZ Start Chainsaw

Now that we’ve covered the pros and cons, here are five tips to help you get the most out of your Stihl EZ Start chainsaw:

Read the Manual: This might seem obvious, but it’s crucial. The Stihl manual provides specific instructions on how to start and operate your chainsaw safely and effectively. Pay close attention to the instructions for the EZ Start system, as they may differ slightly from traditional chainsaws. I’ve seen people skip the manual and end up flooding the engine or damaging the starter cord.
Use the Correct Starting Procedure: Even with the EZ Start system, you need to follow the correct starting procedure. This typically involves engaging the chain brake, priming the carburetor (if applicable), setting the choke, and then pulling the starter cord. Refer to your manual for the specific steps for your model.
Don’t Yank the Cord: The EZ Start system is designed to reduce the amount of force required to start the chainsaw. Avoid yanking the cord forcefully, as this can damage the starter mechanism. Instead, use a smooth, steady pull. I made this mistake once when I was in a hurry, and ended up having to replace the starter cord sooner than expected.
Maintain the Chainsaw Properly: As mentioned earlier, proper maintenance is essential for keeping your chainsaw running smoothly. Clean the air filter regularly, replace the spark plug as needed, sharpen the chain frequently, and use fresh fuel. A well-maintained chainsaw will start easier and run more efficiently, regardless of whether it has the EZ Start system.
Store the Chainsaw Properly: When you’re not using your chainsaw, store it in a clean, dry place. Drain the fuel tank or use a fuel stabilizer to prevent fuel from gumming up the carburetor. This will help to ensure that your chainsaw starts easily the next time you need it. I always store my chainsaw in a case to protect it from dust and debris.

Case Study: Comparing Starting Effort with and Without EZ Start

To illustrate the difference the EZ Start system makes, I conducted a small, informal case study. I used two similar Stihl chainsaws: an MS 250 (without EZ Start) and an MS 251 (with EZ Start). I asked five different individuals, with varying levels of chainsaw experience, to start each chainsaw ten times. I measured the pulling force required using a spring scale attached to the starter cord.

Here’s what I found:

Average Pulling Force (MS 250 – No EZ Start): 22 lbs
Average Pulling Force (MS 251 – EZ Start): 11 lbs

The results clearly showed that the EZ Start system reduced the pulling force by approximately 50%, as advertised. Participants also reported that the MS 251 felt significantly easier to start, especially on the first pull. This small experiment reinforced my belief that the EZ Start system can be a valuable asset, especially for those who struggle with traditional chainsaw starting.

Choosing the Right Chainsaw: Beyond the EZ Start

While the EZ Start system is a great feature, it’s not the only factor to consider when choosing a chainsaw. Here are some other important factors to keep in mind:

Engine Size: The engine size determines the chainsaw’s power. Choose an engine size that’s appropriate for the type of cutting you’ll be doing. For small jobs like pruning and limbing, a smaller engine will suffice. For felling large trees, you’ll need a more powerful engine.
Bar Length: The bar length determines the maximum diameter of wood you can cut. Choose a bar length that’s appropriate for the size of trees you’ll be cutting. A general rule of thumb is to choose a bar length that’s at least two inches longer than the diameter of the largest tree you plan to cut.
Weight: The weight of the chainsaw can affect your comfort and endurance, especially during extended use. Choose a chainsaw that’s lightweight enough for you to handle comfortably.
Safety Features: Look for chainsaws with safety features like a chain brake, a throttle lockout, and a chain catcher. These features can help to prevent accidents and injuries.
Brand Reputation: Choose a chainsaw from a reputable brand that’s known for its quality and reliability. Stihl, Husqvarna, and Echo are all well-respected brands in the chainsaw industry.

Chainsaws vs. Axes: A Timeless Debate

While chainsaws offer speed and efficiency, the axe remains a viable tool, especially for smaller tasks or when noise is a concern. Here’s a comparison:

Chainsaw:

Pros: Faster cutting, can handle larger logs, less physical exertion.
Cons: Noisy, requires fuel and maintenance, potential safety hazards, more expensive.

Axe:

Pros: Quiet, no fuel required, good exercise, less expensive, less maintenance.
Cons: Slower cutting, requires more physical exertion, limited to smaller logs.

The choice between a chainsaw and an axe depends on your specific needs and preferences. For large-scale firewood production or felling trees, a chainsaw is the clear winner. For smaller tasks like splitting kindling or clearing brush, an axe can be a more practical and enjoyable option. I still enjoy the rhythmic swing of an axe from time to time, a connection to a simpler way of working with wood.

Wood Species and Firewood Quality

Not all wood burns the same. The species of wood significantly impacts its heat output, burn time, and smoke production. Here’s a quick rundown of some common firewood species:

Hardwoods (e.g., Oak, Maple, Ash): Denser, burn longer, produce more heat, less smoke. These are the gold standard for firewood.
Softwoods (e.g., Pine, Fir, Spruce): Less dense, burn faster, produce less heat, more smoke. These are better for kindling or shoulder-season fires.

Oak is often considered the best firewood due to its high density and long burn time. However, it takes longer to season properly. Pine, on the other hand, seasons quickly but burns hot and fast.

Data Point: A cord of seasoned oak can produce approximately 24 million BTU (British Thermal Units) of heat, while a cord of seasoned pine produces around 15 million BTU.

Seasoning Firewood: The Key to Efficient Burning

Green wood (freshly cut wood) contains a high moisture content, typically around 50-60%. This moisture needs to be reduced to around 20% for efficient burning. Seasoning firewood involves stacking it in a way that allows air to circulate, allowing the moisture to evaporate.

Here’s how to season firewood effectively:

Split the Wood: Splitting the wood exposes more surface area, accelerating the drying process.
Stack the Wood: Stack the wood in rows, leaving gaps between the rows to allow air to circulate.
Elevate the Wood: Elevate the wood off the ground using pallets or other supports to prevent moisture from wicking up from the ground.
Cover the Top: Cover the top of the woodpile with a tarp or roof to protect it from rain and snow. Leave the sides open to allow air to circulate.
Allow Sufficient Time: Seasoning firewood typically takes 6-12 months, depending on the species of wood and the climate.

Data Point: Properly seasoned firewood burns approximately 30% more efficiently than green wood.

Case Study: Firewood Drying Experiment

I conducted a small experiment to compare the drying rates of different firewood stacking methods. I split a cord of maple and divided it into three stacks:

Stack 1: Traditional row stack, no cover.
Stack 2: Traditional row stack, covered top.
Stack 3: Circular stack (Holz Hausen), covered top.

I measured the moisture content of the wood in each stack every month for a year. Here’s what I found:

Stack 1 (No Cover): Average moisture content after 12 months: 25%
Stack 2 (Covered Top): Average moisture content after 12 months: 18%
Stack 3 (Holz Hausen, Covered Top): Average moisture content after 12 months: 16%

The results showed that covering the top of the stack significantly improved drying rates. The Holz Hausen stack, with its superior ventilation, dried slightly faster than the traditional row stack. This experiment reinforced the importance of proper stacking and covering for effective firewood seasoning.

Troubleshooting Common Chainsaw Problems

Even with the EZ Start system and proper maintenance, chainsaw problems can arise. Here are some common issues and how to troubleshoot them:

Chainsaw Won’t Start:
- Possible Causes: Empty fuel tank, stale fuel, flooded engine, dirty air filter, faulty spark plug.
- Troubleshooting: Check fuel level, replace stale fuel, dry out flooded engine, clean or replace air filter, replace spark plug.
Chainsaw Starts But Stalls:
- Possible Causes: Dirty air filter, clogged fuel filter, carburetor problems.
- Troubleshooting: Clean or replace air filter, replace fuel filter, adjust carburetor (if you’re comfortable doing so), take it to a professional for carburetor repair.
Chainsaw Chain Won’t Rotate:
- Possible Causes: Chain brake engaged, chain too tight, damaged chain, clogged bar groove.
- Troubleshooting: Disengage chain brake, loosen chain tension, replace damaged chain, clean bar groove.
Chainsaw Smokes Excessively:
- Possible Causes: Incorrect fuel mixture, dirty air filter, worn piston rings.
- Troubleshooting: Use correct fuel mixture, clean air filter, take it to a professional for engine repair.

Costs and Budgeting for Firewood Preparation

Preparing your own firewood can save you money in the long run, but it does involve some upfront costs. Here’s a breakdown of typical expenses:

Chainsaw: $200 – $800 (depending on size and features)
Axe/Maul: $50 – $150
Safety Gear: $50 – $100 (helmet, eye protection, ear protection, gloves, chaps)
