Ferguson TE20 Distributor & Points Setup Guide

Ignition Timing, Points Gap & Spark Adjustment

Correct distributor setup is critical for reliable starting and smooth engine performance on your Ferguson TE20. Incorrect points gap or timing can cause hard starting, backfiring, weak spark, and loss of power.

Use this guide to correctly service and adjust your TE20 ignition system.

🔧 Tools You’ll Need

  • Feeler gauge

  • Flat screwdriver

  • Spanner set

  • Timing light (optional but recommended)

  • Clean rag

  • Replacement points & condenser (if required)

Step 1️⃣ – Inspect the Distributor

  1. Remove distributor cap

  2. Inspect for cracks or carbon tracking

  3. Check rotor arm condition

  4. Inspect HT leads for wear

Replace any damaged components before proceeding.

Step 2️⃣ – Setting the Points Gap

Correct points gap is essential for proper spark timing and coil performance.

Recommended Points Gap:

0.015” (15 thou)

How to Set:

  1. Rotate engine until points are fully open

  2. Insert feeler gauge (0.015\\\")

  3. Loosen fixing screw

  4. Adjust until slight drag on gauge

  5. Tighten screw securely

Incorrect gap can cause:

❌ Weak spark
❌ Coil overheating
❌ Hard starting
❌ Rough running

Step 3️⃣ – Check Ignition Timing

Correct timing ensures spark occurs at the proper moment.

Static Timing Method:

  1. Turn engine to Top Dead Centre (TDC)

  2. Loosen distributor clamp

  3. Slowly rotate distributor

  4. Tighten when points just begin to open

For best results, use a timing light once running.

Step 4️⃣ – Check the Ignition Coil

Ensure the correct coil is fitted:

Electrical System Correct Coil
Original 6V 6V coil
12V conversion 12V non-ballast coil
12V with resistor Ballast-type coil

Using the wrong coil can cause overheating and weak spark.

Step 5️⃣ – Replace Condenser (If Needed)

A failing condenser can cause:

  • No spark

  • Weak spark

  • Points burning quickly

  • Engine cutting out

If in doubt, replace both points and condenser together.

Common TE20 Ignition Problems

Symptom Likely Cause
Hard starting Incorrect timing
No spark Failed coil or condenser
Backfiring Incorrect timing
Rough running Incorrect points gap
Coil overheating Wrong coil type

Recommended Agline Products

  • 12V Lucas-style ignition coil

  • Contact points

  • Condenser

  • Spark plugs

  • HT leads

Why Proper Distributor Setup Matters

Correct ignition setup:

✔ Improves starting
✔ Increases fuel efficiency
✔ Reduces misfiring
✔ Extends ignition component life
✔ Improves overall engine performance
