Echo Weed Eater Coil Troubleshooting (5 Pro Fixes For Power Loss)

Echo Weed Eater Coil Troubleshooting: 5 Pro Fixes for Power Loss

When your Echo weed eater starts losing power, the ignition coil is often the prime suspect. This small but mighty component is responsible for generating the high-voltage spark that ignites the fuel-air mixture in the engine. Without a properly functioning coil, your weed eater won’t run smoothly, if at all. Here are five pro fixes to troubleshoot and address power loss issues related to the coil:

1. Visual Inspection and Cleaning

Why It’s Important: The first step in any troubleshooting process should always be a thorough visual inspection. Dirt, debris, and corrosion can all interfere with the coil’s ability to function correctly.

How to Perform It:

Disconnect the spark plug wire: This is crucial for safety. Never work on the ignition system with the spark plug connected.
Locate the ignition coil: The coil is typically located near the flywheel, often mounted to the engine block.
Inspect for damage: Look for cracks, breaks, or any signs of physical damage to the coil.
Clean the coil: Use a clean cloth or brush to remove any dirt, debris, or corrosion from the coil and the surrounding area. A wire brush can be helpful for stubborn corrosion.
Check the air gap: The air gap is the distance between the coil and the flywheel. Refer to your Echo weed eater’s service manual for the correct air gap specification (usually around 0.010-0.014 inches). Use a feeler gauge to check the gap and adjust as needed.

My Experience: I once had an Echo weed eater that was sputtering and losing power intermittently. After a quick visual inspection, I found a thick layer of dirt and grime caked around the coil. After cleaning it thoroughly and adjusting the air gap, the weed eater ran like new. This simple fix saved me the cost of a new coil and a trip to the repair shop.

2. Testing Coil Resistance with a Multimeter

Why It’s Important: A multimeter can be used to measure the electrical resistance of the coil, which can help determine if it’s functioning correctly.

How to Perform It:

Set the multimeter to measure resistance (Ohms).
Locate the primary and secondary coil terminals: Refer to your Echo weed eater’s service manual for the location of these terminals.
Measure the resistance between the primary terminals: The resistance should be within the range specified in the service manual.
Measure the resistance between the secondary terminal (spark plug wire connection) and the engine ground: Again, the resistance should be within the specified range.

Interpreting the Results:

Zero resistance: Indicates a short circuit.
Infinite resistance: Indicates an open circuit.
Resistance outside the specified range: Indicates a faulty coil.

Relating to Other Metrics: Coil resistance is directly related to engine performance. A faulty coil can lead to poor spark, incomplete combustion, and ultimately, power loss.

Data-Backed Insight: I once used a multimeter to diagnose a coil issue on a project where we were clearing brush for a new firewood storage area. The initial resistance readings were significantly outside the manufacturer’s specifications. Replacing the coil not only restored the weed eater’s power but also improved our efficiency in clearing the brush, saving us approximately 2 hours of labor.

3. Checking the Spark Plug Wire and Boot

Why It’s Important: The spark plug wire and boot connect the coil to the spark plug. A damaged or corroded wire or boot can prevent the spark from reaching the plug, leading to power loss.

How to Perform It:

Inspect the spark plug wire: Look for cracks, breaks, or any signs of damage.
Inspect the spark plug boot: Check for cracks, tears, or corrosion.
Test the spark plug wire resistance: Use a multimeter to measure the resistance of the spark plug wire. It should be within the range specified in the service manual.
Ensure a secure connection: Make sure the spark plug wire is securely connected to both the coil and the spark plug.

Practical Example: I’ve seen cases where the spark plug boot had deteriorated due to exposure to the elements. This caused intermittent power loss, especially in damp conditions. Replacing the boot solved the problem immediately.

4. Evaluating the Flywheel Key

Why It’s Important: The flywheel key is a small metal piece that connects the flywheel to the crankshaft. If the key is sheared or damaged, it can disrupt the timing of the engine, leading to power loss.

How to Perform It:

Remove the flywheel cover: This will expose the flywheel and the flywheel key.
Inspect the flywheel key: Look for any signs of damage, such as a sheared or broken key.
Replace the flywheel key if necessary: If the key is damaged, it must be replaced with a new one.

Case Study: I had a project where we were cutting firewood on a steep hillside. The constant jarring and vibration caused the flywheel key on one of our chainsaws to shear. This resulted in a significant loss of power and made the chainsaw difficult to start. Replacing the flywheel key restored the chainsaw to its full operating capacity.

5. Replacing the Ignition Coil

Why It’s Important: If all other troubleshooting steps have failed, it’s likely that the ignition coil itself is faulty and needs to be replaced.

How to Perform It:

Disconnect the spark plug wire.
Remove the old ignition coil: Unscrew the bolts or screws that hold the coil in place and disconnect any wires.
Install the new ignition coil: Install the new coil in the same location as the old one, making sure to connect any wires properly.
Set the air gap: Use a feeler gauge to set the air gap between the coil and the flywheel to the specification in the service manual.
Connect the spark plug wire.

Actionable Insights: When replacing the ignition coil, it’s crucial to use a high-quality replacement part. Cheaper aftermarket coils may not perform as well or last as long as OEM (Original Equipment Manufacturer) coils.
