MS 171 Stihl Chainsaw Tips (5 Pro Hacks For Smooth Starts)

Did you know that a single dull chainsaw chain can increase your fuel consumption by up to 20%? That’s a fact that hit me hard a few years back when I was knee-deep in a firewood project, and my MS 171 Stihl was guzzling gas like it was going out of style. Let’s dive into how to keep your MS 171 purring like a kitten and starting smoother than a hot knife through butter.

MS 171 Stihl Chainsaw Tips (5 Pro Hacks for Smooth Starts)

The Stihl MS 171 is a workhorse of a chainsaw, perfect for homeowners and light-duty woodcutting tasks. I remember buying mine years ago, thinking it would be a simple “plug and play” situation. Boy, was I wrong! Even a reliable machine like the MS 171 needs a little TLC to ensure it starts smoothly and runs efficiently. This article is packed with pro hacks and cost-saving tips, drawn from my experience and industry best practices, to help you master your MS 171.

Understanding the MS 171

Before we get into the hacks, let’s quickly recap what makes the MS 171 tick. It’s a lightweight, gasoline-powered chainsaw designed for felling small trees, limbing, and cutting firewood. Its key features include:

Displacement: Around 30.1 cc
Power Output: Approximately 1.8 bhp
Weight: Roughly 9.5 lbs (without bar and chain)
Bar Length: Typically available in 14″ or 16″

These specs make it ideal for smaller jobs. However, pushing it beyond its limits will only lead to frustration and potentially damage the saw. Think of it like this: it’s a nimble sports car, not a heavy-duty truck.

Hack 1: The Perfect Fuel Mix (and Why It Matters)

This is where many people stumble. The MS 171, like most two-stroke engines, requires a precise mixture of gasoline and oil. Stihl recommends a 50:1 ratio, meaning 50 parts gasoline to 1 part two-stroke oil.

Why is this so crucial?

Lubrication: The oil lubricates the engine’s internal components, preventing wear and tear.
Cooling: The oil also helps dissipate heat, preventing overheating.
Engine Life: Using the wrong mixture can drastically shorten the engine’s lifespan.

My Personal Experience:

I once used a slightly richer mixture (thinking more oil was better). The result? A smoky, sputtering engine that was hard to start and lacked power. It took me a good hour of fiddling to get it running right again.

Data and Statistics:

According to a study by the Society of Automotive Engineers (SAE), incorrect fuel mixtures are responsible for up to 70% of two-stroke engine failures. That’s a staggering number!

Actionable Steps:

Use High-Quality Two-Stroke Oil: Don’t skimp on the oil. Opt for a reputable brand specifically designed for air-cooled two-stroke engines. Stihl’s own oil is a good choice, but other brands like Echo and Husqvarna also offer excellent products.
Mix the Fuel Correctly: Invest in a fuel mixing container with clear markings for the 50:1 ratio. Don’t eyeball it! Precision is key.
Use Fresh Fuel: Gasoline degrades over time, especially when mixed with oil. Only mix enough fuel for a few weeks of use. If you won’t be using the saw for a while, drain the fuel tank and carburetor.
Avoid Ethanol-Blended Fuels (If Possible): Ethanol can damage small engine components. If you must use ethanol-blended fuel, add a fuel stabilizer to prevent problems.

Cost Implications:

Using the correct fuel mixture not only extends the life of your chainsaw but also saves you money in the long run. Here’s a breakdown:

Engine Repair: A major engine repair can easily cost $200-$400.
Fuel Efficiency: A properly running engine is more fuel-efficient.
Downtime: Avoid the frustration and lost productivity of a chainsaw that won’t start.

Fuel Cost Analysis:

Let’s assume you use 1 gallon (3.785 liters) of fuel per month. Using a high-quality two-stroke oil at a 50:1 ratio will cost you approximately $2-3 per gallon of mixed fuel. While this might seem like a small expense, it’s a worthwhile investment compared to the cost of engine repairs. I typically spend about $30 a year on two-stroke oil, and that’s a price I’m happy to pay for peace of mind.

Hack 2: Mastering the Starting Procedure (The Right Way, Every Time)

The starting procedure for the MS 171 is straightforward, but it’s crucial to follow it correctly. Here’s the step-by-step guide:

Engage the Chain Brake: This is a safety precaution to prevent the chain from moving during starting.
Set the Master Control Lever: This lever controls the choke and throttle. For a cold start, move it to the “choke” position (usually fully extended).
Pump the Primer Bulb: Press the primer bulb (the small, clear bulb near the carburetor) several times until you see fuel flowing through it. This primes the carburetor with fuel.
Pull the Starter Cord: Grip the starter handle firmly and pull the cord briskly. Don’t yank it! Pull it smoothly and steadily.
Listen for the “Pop”: After a few pulls, the engine should “pop” or briefly fire. This indicates that fuel is reaching the combustion chamber.
Move the Master Control Lever to the “Half-Choke” Position: This allows more air into the mixture.
Pull the Starter Cord Again: Continue pulling the starter cord until the engine starts and runs smoothly.
Disengage the Chain Brake: Once the engine is running smoothly, disengage the chain brake.
Warm-Up: Let the engine warm up for a few minutes before putting it under load.

Common Mistakes (and How to Avoid Them):

Over-Choking: Too much choke can flood the engine, making it difficult to start. If you suspect flooding, remove the spark plug and pull the starter cord several times to clear the cylinder.
Yanking the Starter Cord: This can damage the starter mechanism. Pull the cord smoothly and steadily.
Ignoring the Primer Bulb: The primer bulb is essential for cold starts. Make sure to pump it until you see fuel flowing through it.

The Warm Start:

If the engine is already warm, you typically don’t need to use the choke. Simply move the master control lever to the “run” position and pull the starter cord.

Cost Implications:

Mastering the starting procedure prevents unnecessary wear and tear on the starter mechanism. Replacing a starter can cost anywhere from $50 to $100, plus labor.

Troubleshooting Starting Problems:

If your MS 171 is still difficult to start, consider the following:

Spark Plug: Check the spark plug for fouling or damage. Replace it if necessary.
Fuel Filter: A clogged fuel filter can restrict fuel flow. Replace it regularly.
Air Filter: A dirty air filter can also restrict airflow. Clean or replace it as needed.
Carburetor: If all else fails, the carburetor may need to be cleaned or rebuilt. This is best left to a qualified technician.
