Chainsaw Ignition System

 The chainsaw ignition system is responsible for generating the high-voltage spark that ignites the fuel-air mixture in the engine's combustion chamber. This spark initiates the combustion process, driving the piston and creating the power necessary for the engine to operate. The ignition system plays a crucial role in the overall performance and starting of the chainsaw. Here's a general overview of how the ignition system of a chainsaw works:

Ignition Coil: The ignition coil is a primary component of the ignition system. It consists of two coils of wire, the primary coil and the secondary coil, wrapped around an iron core. The primary coil is connected to the engine's power source (usually the magneto or flywheel) and is responsible for storing and amplifying electrical energy.

Flywheel/Magneto: The flywheel is a rotating component attached to the crankshaft of the engine. It contains a permanent magnet or magnets that generate a magnetic field as the flywheel spins. This changing magnetic field induces a voltage in the primary coil of the ignition coil.

Trigger Mechanism: The trigger mechanism, often referred to as the "points" or "contact breaker," controls the timing of the ignition spark. In older chainsaw models, the trigger mechanism consists of a set of mechanical contacts that open and close as the flywheel rotates. In modern chainsaws, electronic ignition systems (CDI - Capacitor Discharge Ignition or digital systems) have largely replaced mechanical points.

Condenser/Capacitor (Optional): In older ignition systems, a condenser (also known as a capacitor) is used to suppress arcing and prolong the life of the points. It stores excess energy from the primary coil and releases it when the points open, aiding in spark generation.

Spark Plug: The spark plug is connected to the secondary coil of the ignition coil. When the ignition system is activated, the high voltage generated in the secondary coil is sent to the spark plug. The spark plug's electrode gap creates a spark that ignites the compressed fuel-air mixture in the engine's combustion chamber.

Spark Plug Wire: The spark plug wire connects the ignition coil to the spark plug. It carries the high voltage from the coil to the spark plug.

Kill Switch: The chainsaw is equipped with a kill switch, also known as an on/off switch, that allows the operator to stop the engine by interrupting the flow of electricity to the ignition system. This is an important safety feature.

Operation of the Ignition System In Chainsaws 

The operation of a chainsaw ignition system involves the following steps:

As the flywheel rotates, it generates a changing magnetic field that induces a current in the primary coil of the ignition coil.

The primary coil stores and amplifies this current.

The trigger mechanism (points or electronic component) determines the timing of the spark by controlling when the primary circuit is interrupted.

When the primary circuit is interrupted, the stored energy in the primary coil is rapidly released to the secondary coil.

The secondary coil amplifies the voltage even further, sending a high-voltage pulse to the spark plug.

The spark plug generates a spark across its electrodes, igniting the fuel-air mixture in the engine's combustion chamber.

Obviously, the chainsaw ignition system is a critical system of a chainsaw's operation, ensuring reliable starting, smooth operation, and efficient power delivery.

What Do Small Engine Mechanics Need To Know About Electronics?

 Small engine mechanics involve a variety of electronics, especially in modern engines. These electronics play a crucial role in engine performance, diagnostics, and overall functionality. Some of the electronics involved in small engine mechanics include:

Ignition System: Modern small engines often use electronic ignition systems, which include components like ignition coils, spark plugs, and electronic control modules (ECMs). These systems generate and control the spark that ignites the fuel-air mixture in the engine's combustion chamber.

Fuel Injection Systems: Electronic fuel injection (EFI) systems have become common in small engines. EFI systems use sensors to measure factors such as engine temperature, air intake, and throttle position to optimize fuel delivery for better efficiency and performance.

Engine Control Module (ECM): The ECM, sometimes referred to as the Engine Control Unit (ECU), is the brain of the engine. It processes sensor data and controls various engine functions, including fuel injection, ignition timing, emissions, and more.

Sensors: Small engines incorporate various sensors to monitor engine conditions and provide data to the ECM. These sensors can include oxygen sensors (O2 sensors), temperature sensors, throttle position sensors, crankshaft position sensors, and more.

Digital Displays: Some small engines feature digital displays that provide information to the operator, such as engine RPM, temperature, oil pressure, and warning indicators.

Diagnostics: Mechanics use specialized diagnostic tools, such as scan tools and code readers, to interface with the engine's electronics. These tools can read error codes, perform diagnostic tests, and help identify issues within the engine's electronic systems.

Electric Start Systems: Many small engines, especially those in lawn mowers, generators, and recreational vehicles, use electric start systems that rely on batteries and solenoids to engage the starter motor.

Safety Systems: Some small engines incorporate safety features controlled by electronics, such as low-oil shutdown systems that prevent engine damage when oil levels are too low.

Charging Systems: Small engines with electrical components (lights, electronics, etc.) often include charging systems that replenish the battery while the engine is running. These systems may include alternators or stators.

Emissions Control Systems: Electronic components play a vital role in emissions control, including catalytic converters and oxygen sensors, which help ensure compliance with environmental regulations.

It's mandatory for small engine mechanics to have a good understanding of these electronic systems to diagnose and repair issues effectively. As technology continues to advance, electronics will likely play an even more significant role in the operation and maintenance of small engines. 

Of course, not all of these electronic components are found in every machine. So...

Chainsaw Fuel Related Problems Common to All Outdoor Power Equipment

Chainsaws and lawn mowers, like any other small engines in outdoor power equipment, can experience various fuel-related problems that affect starting and running performance. Here are some common issues related to chainsaw fuel systems and their potential causes:

How Fuel Affects Chainsaw Starting When Chainsaw Won't Start

Stale Fuel: If the mower has been sitting with fuel in the tank for an extended period, the fuel can become stale and less effective. Stale fuel doesn't burn well, making it difficult for the engine to start.

Clogged Fuel Filter: A clogged fuel filter can prevent fuel from reaching the carburetor, leading to starting issues.

Dirty Carburetor: Dirt or debris in the carburetor can block the fuel passages and jets, affecting the fuel-air mixture and making the engine hard to start. So can old fuel, as it gets gummy and messes up carburetors and fuel lines.

How Fuel Can Cause Engine Stalling or Running Rough

An engine can stall or run rough when it's not getting enough, or proper mixture of, combustible ingredients.

Water in Fuel: Moisture can enter the fuel tank, causing the engine to stall or run rough. This could be due to leaving the mower in a rainy environment or using a fuel container that has water in it.

Clogged Air Filter: A dirty air filter can disrupt the air-to-fuel ratio, leading to rough running or stalling.

Carburetor Issues: A faulty or misadjusted carburetor can cause poor fuel delivery, leading to rough engine operation.

Choke: If the engine is choked when it should not be, or choked too much it'll run badly and eventually stall. The fuel to air mixture cannot be too rich or too lean for smooth running engines. An engine needs less air to start, or as it warms up, so the choke needs to be closed to choke off the air supply somewhat. Then when the engine is warm, the choke must be fully open to allow ample air to mix with the fuel.

Fuel Problems Can Cause Excessive Exhaust Smoke

Over-Choked Engine: If the engine is over-choked, it can cause excessive fuel to enter the combustion chamber, leading to black smoke in the exhaust.

Oil in the Fuel: Accidentally adding oil to the fuel tank instead of the oil reservoir can cause blue or white smoke in the exhaust.

Fuel Leaks Are Common Fuel Related Problems in Chainsaws and Mowers

Damaged Fuel Lines or Fittings: Cracked or damaged fuel lines or fittings can cause fuel leaks, which are not only wasteful but also hazardous.

Can Fuel Cause Lack of Power?

Yes.

Dirty Fuel System: A dirty fuel system, including the fuel tank, fuel lines, and carburetor, can restrict fuel flow, resulting in reduced engine performance.

Improper Fuel Mixture: Using the wrong fuel-to-oil ratio (in 2-stroke engines) can affect engine power and cause damage.

How To Troubleshoot Chainsaw Fuel System Problems

To troubleshoot and fix any of the above issues, follow these steps:

Always use fresh, clean fuel. If yours has been sitting for some extended amount of time, then dump it and get fresh gas from the pumps. Also, if you suspect water in the fuel, drain the tank and refill with fresh fuel.

Check the fuel lines and fittings for any signs of damage or leaks. The problem could be that the gas is not getting to the destination, or not in sufficient quantity or speed. 

Replace the fuel filter regularly as recommended by the manufacturer. Clogs are a major cause of fuel flow problems and they're often caused by a dirty filter. 

Engines have to breathe too! Ensure the carburetor is clean and properly adjusted so it can manage the proper air to fuel mixture. Also, clean or replace the air filter as needed.

Chainsaw Bag Alert

Recently, while poking around searching for chainsaw parts vendors, we discovered this chainsaw bag for carrying saws with their bar and chain still attached. We've always sold plastic hard-case chainsaw carrying cases in store and online, and it seemed a logical way to carry a saw mostly because of the sharpness of the teeth on the chain. However, we think these softer chainsaw bags are quite handy and valuable. 

Toting a chainsaw around in a hard case is a bit cumbersome, and when empty, you need to store that plastic carrying case somewhere that it won't "walk away", if you know what I mean. A chainsaw duffle bag, on the other hand, is easier to conceal. Not only is storage of the empty tote bag much easier than a hard case, but it's lighter to lug around the field. It's just easier to carry a saw in one of these.

We find these handy chainsaw bags, as pictured below, to be very convenient, waterproof, unbranded, easy to store, and not expensive. Dark enough to not get covered in dirt on the first day. Available in all black and in red. 

Unbranded Chainsaw Bag

Unbranded is good, because it won't matter if your saw is a Husqvarna, Stihl, Echo, Shindaiwa, McCulloch, Craftsman, Ryobi, Dewalt or whatever. It really doesn't matter. This is just a plain good way to carry a chainsaw. Heck, you're probably already wearing a hat with that name brand on it right now, so you're already representing. Haha!

Another reason why using a no name tote to carry your saw is good idea, is that it's less noticeable, so less likely to get pilfered. Consider one of these chainsaw bags to be part of your security strategy.

Waterproof Chainsaw Bag - Solid Chainsaw Storage For Home Chainsaw users or Lumberjacks

If only there was a chainsaw bag that would be made of tough enough material to carry a saw with the bar and chain on, instead of the dumb plastic boxes. Oh wait! There is one! You're lookin' at it (above).

Made of heavy duty oxford cloth, a tote bag like this should withstand the test of the work for which it's intended. Suitable for homeowner saws and for pro arborists and tree services to use while felling trees on job sites.

Lug your saw around without the angry plastic case bangin' into the side of your leg all the time, toss it into the open bed of your truck in exposed weather, unzip it and pull that pride and joy out for work. EASY! 

• 100% brand new and high quality.
• Made of heavy duty oxford cloth, durable, wear-resistant and waterproof.
• Portable design, you can carry it anywhere by hand.
• Long zipper design makes it is easy to store and take out your chainsaw.
• Great storage bag to protect chainsaws from dirt and dust and avoid being accidentally scratched.

I think you'll love this tote bag for chainsaws. We do.

TL;DR Why do we love the duffle bag for saws idea? They're waterproof, light, easy to carry, stealthy, cooler than a box, inexpensive.

Shut Up & Take My Money

Full Disclosure: We'll get a little wee commision if you buy one, but that's not why we're sending you over there to buy one... they're just cool.

Recession Spending on Chainsaw Parts

Daytona Beach, FL There may be some indication that there is a growing trend of recession spending on chainsaw parts and other outdoor power equipment parts. At HLSupply, revenue in the second quarter of 2022 may indicate that the pending recession (or is it already current?) might indicate that hard working folks are spending on parts to repair their yard and tree machines instead of buying new equipment when there are breakages or deficiencies. In April and May, outdoor power equipment parts sales at HLSupply were closer, though still far below the same months of 2021. However, in these first 6 days of June, sales of chainsaw parts et cetera are almost equal to the first six days of June 2021. Are people being more cost conscious with their outdoor power equipment expenses due to the recession? Is the everyday person watching expenses of all other things similarly due to the recession? It seems that everything points to the decision to buy chainsaw parts and fix your equipment is wiser than buying new. Why? Inflation is too high now, and on top of that there are still factors effecting prices and delivery times due to COVID, while equipment manufacturers are raising their new equipment prices frequently and yet HLSupply prices of chainsaw parts and other parts are mostly the same. Inflation is way up with great effect on the cost of living, gas prices are up a lot, and we are still in a housing bubble. Will that bubble POP soon too? Sadly, the guesstimates are "YES". Some argue that the recession isn't here yet. Others have concluded that certain economic facts indicate that a recession is looming. Still others claim the recession is already upon us. This may get worse than it already is now in mid-2022. Leave a comment below about your spending habits during a recession. Do you cut back on anything? If there are tools of your trade or hobby or lifestyle that require a little more attention than just plain old maintenance, such as repairs or replacement, what will YOU do? Can you even afford to put gas in your chainsaw right now? LOL I mean $4.75/gallon of regular 87 octane fuel is outrageous. Right?
