Easy Start Chainsaws: Switching Your Stihl To EZ Start (Pro Tips)

I’ll never forget the day I nearly threw my brand new Stihl chainsaw into the lake. It was a crisp autumn morning, perfect for cutting firewood, but the darn thing just wouldn’t start. I pulled, and pulled, and pulled until my arm felt like it was going to fall off. My frustration was boiling over, and I was seriously questioning my decision to upgrade to a “professional” model. Little did I know, the solution was simpler than I imagined: understanding the EZ Start system and how to properly switch my Stihl chainsaw to it.

Understanding the Stihl EZ Start System

The Stihl EZ Start system is a game-changer for anyone who’s struggled with starting a chainsaw. It’s designed to reduce the amount of force needed to pull the starter rope, making it much easier to get the engine running. This is achieved through a spring-assisted mechanism that smooths out the starting process.

How EZ Start Works

The EZ Start system works by storing energy as you pull the starter rope. This stored energy is then released to assist in turning the engine over, requiring significantly less effort from you. Think of it like a mini-turbocharger for your starting process.

Benefits of Using EZ Start

Reduced Effort: The most obvious benefit is the reduced physical strain. I can start my chainsaw multiple times in a row without feeling like I’ve just completed an arm workout.
Easier Starts in Cold Weather: Cold engines are notoriously difficult to start. EZ Start makes cold-weather starts much more manageable.
Less Wear and Tear: Because you’re not yanking on the starter rope as hard, there’s less stress on the starter components, potentially extending their lifespan.

Identifying if Your Stihl Chainsaw Has EZ Start

Not all Stihl chainsaws come with EZ Start. Here’s how to check if your model has it:

Look for the “E” designation: Stihl models with EZ Start often have an “E” in their model name (e.g., MS 251 C-BE).
Check the starter housing: The starter housing on EZ Start models is often slightly larger and may have a different design.
Consult your owner’s manual: The owner’s manual will clearly state whether your chainsaw has the EZ Start system.

Switching Your Stihl Chainsaw to EZ Start: A Step-by-Step Guide

Before attempting to switch to EZ Start, ensure your chainsaw is off and the chain brake is engaged. This is a crucial safety precaution.

Step 1: Preparing Your Chainsaw

Safety First: Always wear gloves and eye protection when working on your chainsaw.
Clean the Area: Clear any debris around the starter housing to prevent it from falling into the engine.
Gather Your Tools: You’ll likely need a screwdriver (usually a Torx or a flathead), a spark plug wrench, and possibly a pair of pliers.

Step 2: Accessing the Starter Housing

Locate the Starter Housing: This is the plastic cover on the side of the chainsaw where the starter rope comes out.
Remove the Starter Housing Screws: Use the appropriate screwdriver to remove the screws holding the starter housing in place. Be careful not to strip the screw heads. Keep the screws in a safe place.

Step 3: Inspecting the Starter Mechanism

Carefully Remove the Starter Housing: Gently pull the starter housing away from the chainsaw. Be mindful of any wires or springs that might be attached.
Identify the EZ Start Components: Look for a spring-loaded mechanism connected to the starter pulley. This is the heart of the EZ Start system.
Check for Damage: Inspect the spring, pulley, and rope for any signs of wear or damage. Replace any damaged components.

Step 4: Switching to EZ Start Mode (If Applicable)

This step largely depends on the model. Some models automatically engage the EZ Start mechanism. Others may have a specific lever or switch. Consult your owner’s manual for the exact procedure.

Automatic Engagement: If your model has automatic engagement, simply ensure all components are clean and functioning correctly.
Lever or Switch Activation: Some models might have a lever or switch that needs to be engaged to activate the EZ Start system. This is less common but worth checking.

Step 5: Reassembling the Starter Housing

Carefully Reattach the Starter Housing: Align the starter housing with the chainsaw body and gently push it into place.
Secure the Screws: Reinstall the screws you removed earlier, tightening them securely but not overtightening.
Test the Starter Rope: Pull the starter rope a few times to ensure it moves smoothly and the EZ Start mechanism is engaged.

Troubleshooting Common EZ Start Issues

Even with EZ Start, you might encounter some problems. Here are a few common issues and how to address them.

Chainsaw Still Hard to Start

Check the Spark Plug: A fouled or worn spark plug can make starting difficult. Clean or replace the spark plug as needed. The spark plug gap for most Stihl chainsaws is around 0.5mm (0.02 inches). I recommend using a feeler gauge to ensure the correct gap.
Fuel Issues: Old or contaminated fuel can also cause starting problems. Always use fresh, high-quality fuel mixed with the correct amount of two-stroke oil (usually a 50:1 ratio). I always use a fuel stabilizer, especially if the chainsaw will be stored for an extended period.
Air Filter: A clogged air filter restricts airflow, making starting difficult. Clean or replace the air filter regularly.
Carburetor Issues: In some cases, the carburetor might need adjustment or cleaning. This is best left to a qualified technician.

Starter Rope is Difficult to Pull

Check for Obstructions: Make sure the starter rope isn’t tangled or obstructed.
Lubricate the Starter Mechanism: A small amount of lubricant can help the starter mechanism move more freely. I use a silicone-based lubricant to avoid attracting dirt.
Inspect the Starter Spring: A weak or broken starter spring can make the rope difficult to pull. Replace the spring if necessary.

Starter Rope Breaks

Replace the Starter Rope: A broken starter rope is a common issue. Replacing it is a relatively simple task. You’ll need a new starter rope of the correct length and diameter. The length will vary depending on the model, but a good starting point is around 3-4 feet.
Inspect the Starter Pulley: Check the starter pulley for any sharp edges or damage that could be fraying the rope.

Maintaining Your Stihl Chainsaw for Optimal Performance

Regular maintenance is key to keeping your Stihl chainsaw running smoothly and ensuring the EZ Start system functions correctly.

Regular Cleaning

Clean After Each Use: Remove sawdust and debris from the chainsaw after each use. Pay particular attention to the air filter, spark plug area, and starter housing.
Use Compressed Air: Compressed air can be helpful for removing stubborn debris.

Lubrication

Lubricate Moving Parts: Regularly lubricate moving parts, such as the chain, guide bar, and starter mechanism.
Use the Right Lubricants: Use high-quality lubricants specifically designed for chainsaws. I prefer using Stihl’s own lubricants, as they are formulated to work best with their equipment.

Sharpening the Chain

Keep the Chain Sharp: A sharp chain cuts more efficiently and puts less strain on the engine. Learn how to sharpen your chain or take it to a professional. I use a chainsaw file and a depth gauge to maintain my chain’s sharpness. The correct filing angle depends on the chain type but is typically around 30 degrees.
Check the Chain Tension: Proper chain tension is crucial for safe and efficient cutting. Adjust the tension as needed. The chain should be snug against the guide bar but still able to be pulled around by hand.

Storing Your Chainsaw Properly

Drain the Fuel: Before storing your chainsaw for an extended period, drain the fuel tank.
Clean the Chainsaw: Clean the chainsaw thoroughly before storing it.
Store in a Dry Place: Store the chainsaw in a dry place to prevent rust and corrosion. I store mine in a case to protect it from dust and damage.

Advanced Tips for Stihl Chainsaw Owners

Beyond the basics, here are some advanced tips that can help you get the most out of your Stihl chainsaw.

Understanding Carburetor Adjustments

The carburetor controls the air-fuel mixture in your chainsaw’s engine. Proper carburetor adjustment is essential for optimal performance.

High (H) and Low (L) Speed Needles: These needles control the fuel mixture at high and low engine speeds, respectively.
Idle Speed Screw (LA): This screw controls the engine’s idle speed.
Adjusting the Carburetor: Adjusting the carburetor is a delicate process. It’s best to consult your owner’s manual or seek professional help. A tachometer can be helpful for setting the correct idle speed, which is typically around 2,800-3,200 RPM.

Choosing the Right Chain and Guide Bar

The right chain and guide bar can significantly improve your chainsaw’s performance and safety.

Chain Type: Different chain types are designed for different cutting tasks. Choose a chain that is appropriate for the type of wood you’ll be cutting.
Guide Bar Length: The guide bar length should be appropriate for the size of the wood you’ll be cutting. A longer guide bar allows you to cut larger trees, but it also requires more power.
Matching Chain and Guide Bar: Ensure that the chain and guide bar are compatible with your chainsaw model.

Using a Chainsaw Mill

A chainsaw mill allows you to turn logs into lumber using your chainsaw.

Attaching the Mill: The mill attaches to the guide bar of your chainsaw.
Cutting Lumber: The mill guides the chainsaw as you cut lumber, ensuring consistent thickness and width.
Benefits of Using a Mill: A chainsaw mill allows you to create lumber from trees that would otherwise be unusable. It’s a great option for small-scale lumber production.
