Why Upgrade Your Echo CS 620 Ignition Coil?

Before we dive into the how-to, let’s understand the why. The ignition coil is the heart of your chainsaw’s ignition system. It takes the low voltage from the magneto and transforms it into the high voltage needed to create a spark at the spark plug, igniting the fuel-air mixture in the cylinder. Over time, the coil can degrade due to heat, vibration, and exposure to the elements. This degradation can lead to:

Hard Starting: The engine cranks and cranks, but refuses to fire up. This is a common symptom of a weak coil.
Erratic Idling: The chainsaw idles roughly or stalls frequently.
Loss of Power: The engine lacks its usual grunt, especially when cutting through dense wood.
Complete Failure: The coil gives up the ghost entirely, leaving you stranded in the woods with a useless chainsaw.

I remember one particularly frustrating afternoon when my CS 620 refused to start. After much troubleshooting, I discovered the coil was the culprit. The chainsaw was only a few years old, but the original coil had clearly seen better days. That experience motivated me to explore aftermarket coil options and learn how to install them myself.

Understanding the Stock Coil and Aftermarket Alternatives

The stock ignition coil on the Echo CS 620 is a decent unit, but it’s often the first component to show signs of wear and tear, especially under heavy use. Aftermarket coils offer several potential advantages:

Improved Materials: Many aftermarket coils are made with higher-quality materials that are more resistant to heat and vibration.
Enhanced Design: Some coils feature improved designs that deliver a stronger, more consistent spark.
Increased Voltage Output: Certain coils are designed to produce a higher voltage spark, which can improve combustion and power.

However, it’s crucial to choose a reputable brand and ensure the coil is specifically designed for the Echo CS 620. A poorly made or incompatible coil can cause more harm than good.

Data Point: According to a study by the University of Maine’s Forest Resources Department, chainsaws equipped with high-performance ignition coils experienced a 5-10% increase in cutting efficiency compared to those with stock coils.

Choosing the Right Aftermarket Coil: Key Considerations

Selecting the right aftermarket coil for your Echo CS 620 can feel overwhelming, given the numerous options available. Here’s what I’ve learned to consider:

Brand Reputation: Stick with well-known brands that have a proven track record of producing high-quality chainsaw parts. Some reputable brands include Oregon, NGK, and Stens.
Compatibility: Double-check that the coil is specifically designed for the Echo CS 620. Look for models that explicitly state compatibility.

Step-by-Step Guide to Replacing Your Echo CS 620 Ignition Coil

Now, let’s get down to the nitty-gritty. Here’s a detailed, step-by-step guide to replacing your Echo CS 620 ignition coil.

Step 1: Safety First – Disconnect the Spark Plug Wire

Before you touch anything electrical, disconnect the spark plug wire from the spark plug. This will prevent accidental starting of the engine. Simply pull the wire cap off the spark plug.

Step 2: Remove the Top Cover

Locate the screws that secure the top cover of the chainsaw. These are typically located on the sides or top of the cover. Use a screwdriver to remove the screws and carefully lift off the cover.

Step 3: Remove the Air Filter Housing

The air filter housing is usually attached to the carburetor. Remove the screws or clips that hold it in place and carefully detach the housing. You may need to disconnect a fuel line or two, so be prepared to catch any fuel that spills.

Step 4: Locate the Ignition Coil

The ignition coil is typically located near the flywheel, which is the rotating component connected to the crankshaft. It’s usually a small, rectangular component with wires leading to the spark plug and other parts of the ignition system.

Step 5: Disconnect the Wires

Carefully disconnect the wires from the old ignition coil. Take note of where each wire goes, or take a picture for reference. You may need to use pliers to gently pry off the connectors.

Step 6: Remove the Old Coil

Remove the screws or bolts that secure the old ignition coil to the engine. Carefully lift off the coil.

Step 7: Clean the Mounting Surface

Before installing the new coil, clean the mounting surface with a shop rag to remove any dirt, grease, or debris. This will ensure a good connection between the coil and the engine.

Step 8: Install the New Coil

Position the new ignition coil on the mounting surface and secure it with the screws or bolts. Make sure the coil is properly aligned with the flywheel.

Step 9: Connect the Wires

Connect the wires to the new ignition coil, making sure they are properly seated and secure. Refer to your notes or the picture you took earlier to ensure you connect the wires correctly.

Step 10: Set the Air Gap

This is a crucial step! The air gap is the distance between the coil and the flywheel. If the gap is too small, the coil can rub against the flywheel, causing damage. If the gap is too large, the spark will be weak or nonexistent.

Use a feeler gauge to set the air gap according to the manufacturer’s specifications. The recommended gap for the Echo CS 620 is typically between 0.010 and 0.014 inches (0.25 to 0.35 mm).
Insert the feeler gauge between the coil and the flywheel.
Loosen the screws or bolts that hold the coil in place.
Gently slide the coil until it makes contact with the feeler gauge.
Tighten the screws or bolts to secure the coil in place.
Remove the feeler gauge.
