Understanding the Power and Capability of the 50cc Class
In the world of outdoor power equipment, engine displacement is measured in cubic centimeters (cc). A 50cc engine sits firmly in the “landowner” or “semi-professional” category. It provides significantly more torque than the smaller 35cc or 42cc models found in big-box stores.
This power level allows you to pull a 20-inch guide bar through thick oak or maple without the engine bogging down. For those living in an RV or a small homestead, this is often the only saw you will ever need. It is versatile enough for limbing small branches but beefy enough for serious firewood production.
The 50cc engine typically utilizes a two-stroke design, meaning it requires a specific mix of gasoline and oil. This design keeps the power-to-weight ratio high, which is essential when you are hiking a mile into the woods to clear a blocked access road. You get professional-grade cutting speed without the professional-grade price tag.
The Advantage of the 20-Inch Bar
Most saws in this class come equipped with a 20-inch bar as standard equipment. This length is ideal because it allows you to cut through most logs in a single pass. It also reduces the amount of bending you have to do while bucking wood on the ground.
A longer bar does require more focus on safety, as the “kickback zone” at the tip is further away from your body. However, for a traveler or homesteader, the 20-inch reach is the sweet spot for versatility. It handles everything from clearing brush to felling medium-sized trees safely.
Maintenance and Care for Your Poulan 50cc Chainsaw
To keep your poulan 50cc chainsaw running at peak performance, you must establish a strict maintenance routine. These machines are engineered for durability, but they rely on clean air and high-quality lubrication to survive the heat of a long work session. Neglecting the basics is the fastest way to ruin a cylinder or dull a chain.
Start by checking your air filter after every four hours of active cutting. Dust and wood chips can quickly clog the intake, causing the engine to run “rich” and lose power. Simply pop the top cover, remove the filter, and tap it against a clean surface or wash it with warm, soapy water if it is a felt-style filter.
Lubrication is the lifeblood of the cutting system. Always ensure your bar oil reservoir is full every time you refill the gas tank. Use a high-tack bar and chain oil that stays on the metal even at high rotational speeds. If you notice smoke coming from the bar, stop immediately and check the oiler ports for clogs.
Mastering the Fuel Mixture
Modern engines are sensitive to the chemicals found in standard pump gas. For a 50cc engine, a 50:1 fuel-to-oil ratio is standard, but always verify this with your specific manual. Using the wrong ratio can lead to carbon buildup or, worse, a seized engine from lack of lubrication.
Whenever possible, use ethanol-free gasoline. Ethanol attracts moisture and can degrade the fuel lines and carburetor diaphragms over time. If you must use gas with ethanol, add a fuel stabilizer to every batch. This is especially important for RVers who might store their saw for months between uses.
Sharpening for Efficiency
A sharp chain is safer than a dull one because it requires less physical force to move through the wood. You should see large, clean wood chips flying off the saw, not fine “flour-like” dust. If you see dust, your cutters are dull and need a touch-up with a round file.
Use a 7/32-inch or 3/16-inch file (depending on your chain pitch) and maintain a consistent 30-degree angle. Give each cutter two or three light strokes, always filing from the inside of the tooth toward the outside. Consistent sharpening extends the life of your guide bar and reduces strain on the engine.
Essential Safety Gear and Field Protocols
Operating a high-torque saw is a serious responsibility that requires the right Personal Protective Equipment (PPE). Never start your saw wearing shorts or sandals. A split-second mistake can lead to a life-altering injury, especially when you are far from medical help in a remote camping spot.
Chainsaw chaps are the most critical piece of gear you can own. These are made of layers of ballistic nylon or Kevlar designed to clog the saw’s drive sprocket instantly upon contact. Pair these with steel-toed boots and a hard hat equipped with a face shield and hearing protection.
Before you make your first cut, clear your workspace of any tripping hazards like loose branches or vines. Identify your “escape path”—a 45-degree angle away from the direction the tree is expected to fall. If you are working alone, always use a satellite messenger or let someone know your exact coordinates and expected return time.
Understanding Kickback
Kickback occurs when the upper quadrant of the bar tip touches an object or becomes pinched. The force of the spinning chain throws the bar upward and backward toward the operator. It happens faster than human reaction time, which is why your saw is equipped with a chain brake.
Always keep your left arm straight with your thumb wrapped firmly around the front handle. This positioning ensures that if the saw kicks up, your hand will naturally hit the brake lever, stopping the chain instantly. Never cut with the tip of the saw, and always be mindful of what is behind the log you are cutting.
Step-by-Step Guide to Starting a Cold Engine
Starting a 50cc engine can be a bit of a workout if you don’t follow the proper sequence. Most modern Poulan models feature a “Spring-Assist” starter which reduces the pulling force required. However, the internal combustion physics remain the same: you need the right mix of air, fuel, and spark.
- Engage the Chain Brake: Push the front handguard forward until it clicks. This prevents the chain from spinning the moment the engine fires.
- Prime the System: Press the primer bulb (purge bulb) 6 to 10 times until you see fuel circulating through the clear return line.
- Set the Choke: Pull the choke lever out to the full position. This closes the air flap to create a fuel-rich environment for a cold start.
- Secure the Saw: Place the saw on level ground. Put your right foot through the rear handle and your left hand on the front wrap-around handle.
- Pull the Cord: Pull the starter rope firmly until you hear the engine “burp” or attempt to start. This usually takes 3 to 5 pulls.
- Half-Choke/Run: Push the choke lever in halfway (or all the way, depending on the model) and pull again. The engine should roar to life.
Once the engine is running, blip the throttle once to release the fast-idle setting. Let the saw warm up for about 30 seconds before you start cutting. This allows the piston and cylinder to expand evenly, preventing premature wear on the engine internals.
Troubleshooting Common Engine Issues in the Wild
When you are miles from a repair shop, you need to be your own mechanic. Most issues with a poulan 50cc chainsaw stem from three things: fuel, air, or spark. If the saw won’t start after dozens of pulls, you have likely “flooded” the engine with too much gasoline.
To fix a flooded engine, push the choke all the way in, engage the chain brake, and hold the throttle wide open while pulling the starter cord. This forces extra air into the combustion chamber to dry out the spark plug. It may take 10 to 15 pulls, but the engine will eventually sputter and clear itself out.
If the saw starts but dies when you give it gas, you likely have a “lean” condition. This is often caused by a tiny hole in the fuel line or a clogged fuel filter inside the tank. Use a piece of bent wire to fish the filter out of the tank and check for debris. Replacing a fuel filter is a five-minute job that can save your entire workday.
The Importance of Spark Plug Maintenance
The spark plug is the window into your engine’s health. Remove the plug using the “scrench” (the combined screwdriver and wrench tool) that came with your saw. A healthy plug should be a light tan or “coffee with cream” color.
If the plug is oily and black, you are using too much oil in your mix or your air filter is clogged. If it is white and blistered, the engine is running too hot and “lean,” which can cause permanent damage. Always carry a spare spark plug in your emergency tool kit when heading into the backcountry.
Real-World Use Cases for the Modern Adventurer
Why would a solo traveler or a van-lifer carry a 50cc chainsaw? The answer lies in access and safety. In many national forests, “dispersed camping” is allowed, but roads can be blocked by fallen timber after a summer storm. Having the power to clear your own path is the ultimate form of travel insurance.
For the homesteader, this tool is the primary way to heat your home. Cutting three or four cords of firewood requires a machine that doesn’t overheat. The 50cc displacement provides the gyroscopic stability needed for straight, even cuts, making the physical labor of wood processing much more efficient.
Survivalists also value the 50cc class for building temporary shelters or “cribbing” during search and rescue operations. In a grid-down scenario, the ability to process fuel and building materials quickly is a high-value skill. This saw bridges the gap between lightweight consumer tools and heavy, expensive professional timber saws.
Frequently Asked Questions About Poulan 50cc Chainsaws
What is the best fuel-to-oil ratio for a 50cc engine?
Most modern Poulan 50cc engines require a 50:1 ratio. This means 2.6 ounces of high-quality 2-cycle air-cooled engine oil for every 1 gallon of 89-octane (or higher) gasoline. Using a pre-mixed engineered fuel like TruFuel is even better for long-term storage.
Can I put a shorter bar on my 50cc saw?
Yes, you can swap the 20-inch bar for an 18-inch or even a 16-inch bar. A shorter bar will make the saw feel more powerful because there is less friction and weight for the engine to overcome. This is a great trick for cutting very dense hardwoods like locust or hickory.
How often should I flip my guide bar?
You should flip your guide bar over every time you sharpen or replace the chain. This ensures that the rails wear evenly on both sides. If you don’t flip the bar, one side will develop a “burr,” causing the saw to cut at an angle rather than straight down.
Why does my chain keep getting loose while cutting?
New chains naturally stretch during their first few heat cycles. This is called “initial break-in.” However, if an old chain keeps loosening, check your oiler. If the chain gets too hot from lack of lubrication, the metal expands and the chain sags. Always check tension when the chain is cool.
Final Thoughts on Mastering Your Equipment
Owning a poulan 50cc chainsaw is a major step toward outdoor self-reliance. It is a tool that demands respect and rewards those who take the time to learn its mechanics. Whether you are clearing a path for your overland rig or stocking up on firewood for a long winter, this machine is a capable partner.
Remember that the most important safety feature of any chainsaw is the operator. Stay focused, wear your PPE, and never cut when you are tired or distracted. Treat your saw with the care it deserves, and it will serve you faithfully for years to come. Now, get out there, clear those trails, and enjoy the freedom that comes with being truly prepared.
