The Mystery of the Blue Lever: Unlocking Your Poulan Pro’s Potential

Ever wrestled with a stubborn chainsaw, pulling and pulling until your arm feels like it’s about to fall off? We’ve all been there. I remember one particularly frustrating afternoon in the backwoods of Maine, trying to drop a few dead ash trees for firewood. My old saw, not a Poulan Pro at the time, refused to start. After an hour of tinkering, I finally realized I had flooded the engine. A simple mistake, but it cost me valuable daylight and a whole lot of sweat. That experience taught me the importance of understanding the nuances of each chainsaw, especially those little levers and buttons that control its operation.

The Poulan Pro 16-inch chainsaw is a popular choice for homeowners and hobbyists alike, known for its affordability and decent performance. But like any piece of machinery, it has its quirks. One of the most common points of confusion is the blue lever. What does it do? How do you use it properly? This guide is designed to demystify that blue lever, providing you with the knowledge and confidence to operate your Poulan Pro safely and efficiently.

Deciphering the Blue: Function and Purpose

The blue lever on your Poulan Pro 16-inch chainsaw is, in most models, the choke lever. Its primary function is to enrich the fuel mixture when starting a cold engine. When the engine is cold, the fuel doesn’t vaporize as easily, making it difficult to ignite. The choke restricts airflow into the carburetor, increasing the ratio of fuel to air. This richer mixture is easier to ignite, helping the engine to start.

However, the specific function can vary slightly depending on the exact model of your Poulan Pro. Some models may integrate the choke function with the starting switch or use a slightly different lever mechanism. Always refer to your owner’s manual for the definitive explanation for your specific chainsaw model.

Why is it blue? Frankly, that’s mostly for easy identification. Blue is a common color-coding choice for starting controls on small engines.

Step-by-Step Guide: Using the Blue Lever for Starting

Here’s a detailed, step-by-step guide to using the blue lever to start your Poulan Pro 16-inch chainsaw:

1. Safety First: Always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, gloves, and sturdy footwear. Ensure the chainsaw is on a stable surface and the chain brake is engaged (pushed forward).
2. Fuel and Oil Check: Before starting, verify that the fuel tank is filled with the correct fuel mixture (typically a 50:1 ratio of gasoline to 2-cycle oil, but always check your manual) and that the chain oil reservoir is full. Using the wrong fuel mixture can damage the engine. I once saw a friend ruin a perfectly good chainsaw by using straight gasoline – a costly mistake that could have been avoided with a little diligence.
3. Choke Engagement: Locate the blue lever. For a cold start, move the blue lever to the “full choke” position. This position is usually indicated by a symbol or the word “CHOKE.” On some models, this may involve pulling the lever out.
4. Priming (If Applicable): Many Poulan Pro models have a primer bulb – a small, clear bulb that you press to draw fuel into the carburetor. Press the primer bulb several times (usually 6-8 pumps) until you see fuel flowing through the clear fuel lines. Don’t over-prime, as this can flood the engine.
5. Starting Position: Place the chainsaw on the ground, ensuring the chain is clear of any obstructions. Hold the saw firmly with one hand on the front handle and place your foot on the rear handle to stabilize it.
6. Pull Starting: Grasp the starter cord handle firmly and pull it sharply and smoothly. Avoid pulling the cord all the way out, as this can damage the recoil mechanism. Continue pulling until the engine sputters or attempts to start.
7. Choke Adjustment: Once the engine sputters, move the blue lever to the “half choke” position (if available) or to the “run” position (if there’s no half-choke setting). This reduces the fuel enrichment.
8. Continued Pulling: Continue pulling the starter cord until the engine starts and runs smoothly.
9. Warm-Up: Allow the engine to warm up for a few seconds before disengaging the chain brake and beginning to cut.
10. Hot Start: If the engine is already warm, you typically don’t need to use the choke. Start the chainsaw with the blue lever in the “run” position.

Troubleshooting Starting Issues:

• Engine Flooded: If you’ve pulled the starter cord repeatedly without success, you may have flooded the engine. To clear a flooded engine, move the blue lever to the “run” position and pull the starter cord several times with the throttle fully open.
• Spark Plug Issues: A faulty spark plug can prevent the engine from starting. Check the spark plug for fouling or damage and replace it if necessary. The correct spark plug gap for most Poulan Pro 16-inch chainsaws is typically between 0.025 and 0.030 inches (0.635 to 0.762 mm).
• Fuel Issues: Stale fuel or a clogged fuel filter can also cause starting problems. Ensure you’re using fresh fuel and that the fuel filter is clean. I recommend using fuel stabilizer, especially if you don’t use your chainsaw frequently. It prevents the fuel from breaking down and gumming up the carburetor.

The Blue Lever and Safety: A Critical Connection

The blue lever, while primarily for starting, also plays a role in chainsaw safety. Understanding its function helps prevent common starting-related accidents.

• Kickback Prevention: A common cause of chainsaw accidents is kickback, which occurs when the tip of the bar contacts a solid object, causing the saw to suddenly thrust back towards the operator. Starting the chainsaw correctly, with the chain brake engaged, helps prevent accidental chain engagement that could lead to kickback.
• Avoiding Runaway Chains: If the chainsaw starts with the choke fully engaged and the throttle partially open, the chain may begin to spin uncontrollably. This is a dangerous situation. Always ensure the chain brake is engaged during starting and be prepared to shut off the engine immediately if the chain starts moving unexpectedly.

Maintenance and the Blue Lever: Keeping Things Running Smoothly

While the blue lever itself doesn’t require specific maintenance, its proper use is crucial for maintaining the overall health of your chainsaw.

• Carburetor Health: Improper choke usage can lead to carburetor problems. Running the engine with the choke fully engaged for extended periods can cause excessive fuel buildup, leading to fouling of the spark plug and carbon deposits in the engine.
• Fuel System Maintenance: Regularly inspect the fuel lines and fuel filter for cracks or clogs. Replace them as needed to ensure a consistent fuel supply to the carburetor. A clogged fuel filter can restrict fuel flow, making it difficult to start the chainsaw, even with the choke engaged.

Data-Backed Insights and Technical Specifications

Here are some data points and technical specifications relevant to the Poulan Pro 16-inch chainsaw and its operation:

• Fuel Mixture: The recommended fuel mixture for most Poulan Pro 16-inch chainsaws is 50:1 (gasoline to 2-cycle oil). Using a leaner mixture (more gasoline, less oil) can lead to engine damage due to insufficient lubrication. Using a richer mixture (less gasoline, more oil) can cause excessive carbon buildup.
• Chain Oil: Use a high-quality bar and chain oil specifically designed for chainsaws. This oil has additives that help it adhere to the chain and prevent excessive wear.
• Spark Plug Gap: The correct spark plug gap is typically 0.025 to 0.030 inches (0.635 to 0.762 mm). A wider gap can result in a weak spark, making it difficult to start the engine. A narrower gap can cause the spark plug to foul more easily.
• Engine Displacement: The engine displacement of the Poulan Pro 16-inch chainsaw is typically around 40-42 cc (cubic centimeters). This is a measure of the engine’s cylinder volume and is directly related to its power output.
• Chain Speed: The chain speed of the Poulan Pro 16-inch chainsaw is typically around 15-17 meters per second (m/s). This is the speed at which the chain moves around the bar and is a key factor in its cutting performance.
• Wood Moisture Content and Starting: Starting a chainsaw in colder temperatures can be more difficult. Wood with higher moisture content, especially when frozen, will require more power to cut, potentially stalling the engine if it’s not warmed up properly. Firewood should ideally have a moisture content of 20% or less for efficient burning. I’ve found that using a moisture meter to check the wood before cutting can significantly improve the chainsaw’s performance and reduce the risk of stalling.
• Industry Standards: Chainsaw safety and operation are governed by various industry standards, such as ANSI B175.1 (American National Standards Institute) for gasoline-powered chainsaws. These standards outline requirements for chainsaw design, manufacturing, and safety features.

Case Study: Blue Lever Success in a Firewood Project

I once helped a friend clear a large pile of storm-downed oak trees for firewood. The trees had been lying on the ground for several months, resulting in a higher-than-normal moisture content. Starting his Poulan Pro 16-inch chainsaw proved challenging, even with the choke fully engaged.

We analyzed the situation and realized the combination of cold weather and high wood moisture content was making it difficult for the engine to ignite. We implemented the following steps:

1. Fresh Fuel: We drained the old fuel and replaced it with fresh fuel mixed with fuel stabilizer.
2. Spark Plug Inspection: We inspected the spark plug and cleaned it thoroughly.
3. Warm-Up Procedure: We used the choke to start the chainsaw and allowed it to warm up for a longer period than usual, about 5 minutes, before attempting to cut any wood.
4. Cutting Technique: We used a slower, more deliberate cutting technique to avoid stalling the engine.

By following these steps, we were able to successfully start and operate the chainsaw, clearing the entire pile of downed trees without any further starting issues. This experience highlighted the importance of understanding the interplay between fuel, spark, choke, and wood conditions when operating a chainsaw.

Practical Tips and Best Practices for Blue Lever Mastery

• Read the Manual: This seems obvious, but many people skip this crucial step. The owner’s manual contains specific information about your chainsaw model, including the exact function and operation of the blue lever.
• Practice Makes Perfect: Familiarize yourself with the starting procedure in a safe and controlled environment before attempting to use the chainsaw in a real-world situation.
• Listen to Your Engine: Pay attention to how the engine sounds when you’re starting it. This can provide valuable clues about whether the choke is properly adjusted and whether the engine is flooded.
• Regular Maintenance: Keep your chainsaw properly maintained, including cleaning the air filter, replacing the spark plug, and sharpening the chain. This will ensure it starts easily and runs smoothly.
• Fuel Storage: Store fuel in a clean, airtight container in a cool, dry place. Use fuel stabilizer to prevent the fuel from breaking down and gumming up the carburetor. I always label my fuel containers clearly with the date and fuel mixture ratio.
• Chain Sharpening: A sharp chain reduces the strain on the engine and makes it easier to cut through wood. Learn how to sharpen your chainsaw chain properly or take it to a professional for sharpening. A dull chain will not only make cutting more difficult, but it can also increase the risk of kickback.

Common Challenges and Solutions

• Altitude: At higher altitudes, the air is thinner, which can affect the fuel-air mixture and make it more difficult to start the chainsaw. You may need to adjust the carburetor to compensate for the altitude. Consult your owner’s manual for instructions on carburetor adjustment.
• Humidity: High humidity can also affect the fuel-air mixture, making it more difficult to start the chainsaw. Ensure the air filter is clean and dry.
• Sourcing Quality Fuel and Oil: In some regions, it can be difficult to find high-quality fuel and 2-cycle oil. Use reputable brands and ensure the fuel meets the specifications outlined in your owner’s manual. I’ve found that synthetic 2-cycle oil provides better lubrication and reduces carbon buildup compared to conventional oil.
• Availability of Replacement Parts: Before purchasing a chainsaw, check the availability of replacement parts, such as spark plugs, fuel filters, and air filters. This will ensure you can keep your chainsaw running smoothly for years to come. Poulan Pro parts are generally readily available, but it’s always good to check.
