The Stihl MS 170 is a popular choice for homeowners and light-duty tasks, known for its reliability and ease of use. But even the best tools can be temperamental. This article isn’t just about getting your MS 170 roaring; it’s about laying the groundwork for efficient and cost-effective wood processing. We’ll delve into ignition tips, maintenance best practices, and, crucially, how to budget and manage the costs associated with your wood processing projects.
Understanding the User Intent: Quick Ignition and Cost-Effective Wood Processing
The intent behind searching for “How to Start a Stihl MS 170 (5 Pro Tips for Quick Ignition)” is twofold:
- Immediate Problem Solving: Users are likely experiencing difficulty starting their chainsaw and need immediate, practical solutions.
- Long-Term Efficiency: They’re also likely interested in maintaining their chainsaw for optimal performance and avoiding costly repairs, which ties into the broader goal of cost-effective wood processing.
5 Pro Tips for Quick Ignition of Your Stihl MS 170
Before we dive into the financial implications, let’s get your saw running. These tips are based on my experience and common issues I’ve seen with the MS 170.
- The Primer Bulb Protocol: The primer bulb is your best friend. Press it firmly 5-6 times until you see fuel entering the bulb. This primes the carburetor with fuel, essential for initial starting. Pro Tip: If it’s cold, a few extra pumps won’t hurt. I’ve found that in sub-freezing temperatures, even 8-10 pumps can make a difference.
- Choke Position Awareness: The choke lever controls the air-fuel mixture. For a cold start, engage the choke fully (pushed all the way out). After a few pulls, the engine might sputter. At that point, move the choke lever to the half-choke position (middle position). This is crucial! Leaving the choke fully engaged for too long will flood the engine.
- The Starting Pull Technique: Don’t yank the starter cord! A smooth, deliberate pull is key. Pull until you feel resistance, then give it a firm, controlled pull. Repeat until the engine sputters. Pro Tip: Make sure the chainsaw is on a stable surface. Holding it in mid-air while pulling can be awkward and inefficient.
- Flooding Prevention: If you’ve flooded the engine (you’ll smell fuel), disengage the choke (pushed all the way in) and pull the starter cord several times. This helps clear the excess fuel. Be patient! It might take 10-15 pulls.
- Spark Plug Check and Fuel Freshness: If all else fails, check the spark plug. A fouled or damaged spark plug won’t ignite the fuel mixture. Replace it if necessary. Also, ensure your fuel is fresh. Old fuel can degrade and cause starting problems. Pro Tip: I always add a fuel stabilizer to my fuel mix, especially if I know the saw will be sitting idle for a while. This prevents fuel degradation.
Cost Considerations: Fuel, Maintenance, and Beyond
Now that your MS 170 is purring like a kitten, let’s talk about the real-world costs of using it for wood processing. This is where things get interesting, and where proper planning can save you a significant amount of money.
Fuel Costs: A Breakdown
Fuel is a recurring expense that often gets overlooked. Here’s how to estimate your fuel costs:
- Fuel Mix Ratio: The Stihl MS 170 typically requires a 50:1 fuel-to-oil ratio. This means 50 parts gasoline to 1 part 2-cycle engine oil.
- Gasoline Prices: Gasoline prices fluctuate wildly. As of October 2024, the average price of regular gasoline in the U.S. is around \$3.50 per gallon (Source: AAA Gas Prices). Prices in Europe and other parts of the world can be significantly higher.
- 2-Cycle Oil Prices: A good quality 2-cycle engine oil will cost around \$10-\$20 per quart.
- Fuel Consumption: The MS 170 is relatively fuel-efficient, but consumption depends on the type of wood you’re cutting and the intensity of use. A reasonable estimate is 0.25 gallons per hour of continuous use.
Example Calculation:
Let’s say you plan to cut firewood for 4 hours.
- Gasoline needed: 4 hours * 0.25 gallons/hour = 1 gallon
- Oil needed: For a 50:1 ratio, you’ll need 1/50th of a gallon of oil for every gallon of gas. That’s approximately 2.5 ounces of oil per gallon of gas.
- Gasoline cost: 1 gallon * \$3.50/gallon = \$3.50
- Oil cost: Assuming a quart of oil costs \$15, and there are 32 ounces in a quart, the cost per ounce is \$15/32 = \$0.47/ounce. Therefore, 2.5 ounces of oil will cost 2.5 * \$0.47 = \$1.18.
- Total fuel cost: \$3.50 + \$1.18 = \$4.68 for 4 hours of cutting.
Data Insight: A study by the U.S. Department of Energy found that optimizing engine efficiency and using high-quality synthetic oil can reduce fuel consumption in small engines by up to 15%. This translates to significant savings over time.
Chainsaw Maintenance: Preventing Costly Repairs
Regular maintenance is crucial for extending the life of your MS 170 and preventing expensive repairs. Here’s a breakdown of common maintenance tasks and their associated costs:
- Chain Sharpening: A dull chain is not only inefficient but also dangerous. You can sharpen the chain yourself with a file (cost: \$10-\$20 for a file kit) or have it professionally sharpened (cost: \$10-\$15 per sharpening). I prefer to sharpen my own chains – it’s a skill every chainsaw owner should learn.
- Air Filter Cleaning/Replacement: A clean air filter ensures proper airflow to the engine. Clean the filter regularly with soap and water. Replace it every 6-12 months (cost: \$5-\$10).
- Spark Plug Replacement: Replace the spark plug annually or as needed (cost: \$5-\$10).
- Bar Lubrication: Use a good quality bar and chain oil to keep the chain lubricated and prevent wear. A gallon of bar and chain oil costs around \$15-\$25.
- Chain Replacement: Chains wear out over time and need to be replaced. A new chain for the MS 170 costs around \$20-\$30.
- Professional Servicing: It’s recommended to have your chainsaw professionally serviced every 1-2 years. This includes a thorough inspection, cleaning, and tune-up (cost: \$50-\$100).
Example Maintenance Budget (Annual):
- Chain sharpening (DIY): \$15 (file wear)
- Air filter: \$7
- Spark plug: \$7
- Bar and chain oil: \$20
- Total: \$49
Data Insight: According to a study by Stihl, regular maintenance can extend the lifespan of a chainsaw by up to 50%. This means you could potentially double the time before needing to replace your MS 170, saving you hundreds of dollars.
The Big Picture: Timber Acquisition and Firewood Preparation Costs

Calculating Volume: Board Feet and Cords
Understanding how to calculate wood volume is essential for budgeting and pricing. Here’s a quick overview:
- Board Foot: A board foot is a unit of volume equal to 144 cubic inches (12 inches x 12 inches x 1 inch). It’s commonly used to measure lumber.
- Cord: A cord is a unit of volume equal to 128 cubic feet. It’s commonly used to measure firewood. A standard cord is typically stacked 4 feet high, 4 feet wide, and 8 feet long.
Formulas:
- Board Feet Calculation (for a log): (Diameter in inches squared * Length in feet) / 144
- Cords Calculation (for a stack of firewood): (Height in feet * Width in feet * Length in feet) / 128
Example:
A log with a diameter of 12 inches and a length of 10 feet contains (12 * 12 * 10) / 144 = 10 board feet.
A stack of firewood that is 4 feet high, 4 feet wide, and 8 feet long contains (4 * 4 * 8) / 128 = 1 cord.
Drying Time: A Crucial Factor for Firewood
Seasoning firewood is essential for efficient burning. Green wood contains a high moisture content, which reduces its heating value and produces more smoke.
- Drying Time: The drying time for firewood depends on the species of wood, the climate, and how the wood is stacked. Generally, it takes 6-12 months for firewood to dry properly.
- Moisture Content: The ideal moisture content for firewood is below 20%. You can use a moisture meter to check the moisture content of your wood.
- Stacking Method: Stacking firewood in a single row, with good air circulation, will speed up the drying process.
Data Insight: A study by the Biomass Energy Resource Center found that properly seasoned firewood can produce up to 30% more heat than green wood. This means you’ll need less firewood to heat your home, saving you money.
