Craftsman 753-06871 Trimmer Ignition Module Assembly

The Craftsman 753-06871 Trimmer Ignition Module Assembly controls spark generation for engine starting, while electrical wear can develop through heat exposure, vibration, and repeated ignition cycles.

This part corrects the following symptoms:

• Engine cranks without producing sufficient spark.

• Trimmer needs repeated pulls before starting.

• Engine stalls from inconsistent ignition output.

• Weak spark causes uneven running.

• Ignition becomes erratic as temperatures increase.

Insufficient Spark Output

Quick Check: Check spark plug connection and ignition lead condition.

Fix Suggestion: Correct loose connections and verify the ignition module mounting position.

Prevention Tip: Keep ignition wiring secured and away from excessive engine heat.

Repeated Starting Attempts

Quick Check: Test spark distribution while working on the trimmer.

Fix Suggestion: Confirm proper module alignment with the flywheel before further testing.

Prevention Tip: Check ignition connections during routine trimmer maintenance periods.

Unexpected Engine Stalling

Quick Check: Observe whether the spark disappears after the engine warms.

Fix Suggestion: Address loose wiring or heat-related module speed changes.

Prevention Tip: Maintain clear airflow around the ignition assembly during operation.

Uneven Engine Operation

Quick Check: Examine the ignition lead for damage or poor contact.

Fix Suggestion: Secure the lead connection and correct any displaced wiring.

Prevention Tip: Avoid pulling or bending ignition wires during maintenance work.

Customer Experience: A customer reported steadier trimmer operation after correcting the ignition module alignment and securing its electrical connections.
