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
-
Remove distributor cap
-
Inspect for cracks or carbon tracking
-
Check rotor arm condition
-
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:
-
Rotate engine until points are fully open
-
Insert feeler gauge (0.015\\\")
-
Loosen fixing screw
-
Adjust until slight drag on gauge
-
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:
-
Turn engine to Top Dead Centre (TDC)
-
Loosen distributor clamp
-
Slowly rotate distributor
-
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 |
