Top 5 Tools for Easy Austin Healey Maintenance

Fix the basics first, before the car writes its own agenda

If you’re new to Big Healey, Austin Healey Sprite or MG Midget ownership, here’s something worth knowing: many familiar running problems can be traced to basic checks or adjustments that have been overlooked.

The best-case beginner tool kit isn’t about rebuilding engines. It’s about getting reliable baselines (ignition and carbs), keeping hydraulics healthy (brakes and clutch), and using the right imperial tools so you don’t round fasteners and spend Sunday evening learning new words.

Top 5 Tools for Easy Austin Healey Maintenance
Part Number Product Name Type Key Benefits Ideal For
TOL157 AF 9 Piece Socket Set (3/8" Drive) Imperial hand tools Correct AF sizing reduces rounded fasteners and frustration Day-to-day maintenance jobs
TOL202 Imperial 8pc Combination Spanner Set Imperial spanners Access where sockets won’t fit, better control on original fasteners Linkages, clamps, awkward access points
TOL104 Gunson Timing Light (Advance Feature) Ignition diagnostic Accurate timing setup improves starting, idle, and drivability Setting a reliable ignition baseline
TOL103 Gunson Carbalancer Carburettor tuning Even airflow gives smoother idle and cleaner pickup Twin or triple carburettor setups
TOL125 Gunson Eezibleed Kit Brake & clutch bleeding One-person bleeding with steady flow and cleaner results Routine hydraulic maintenance
TOL157 AF 9 piece socket set 3/8 inch drive for Austin Healey maintenance

1) AF 9 Piece Socket Set – 3/8" drive

Part Number: TOL157

This is one of the tools you’ll probably reach for most often, and it quietly prevents a lot of beginner pain.

A good AF socket set means you stop “making do” with near-enough sizes. On a classic, that’s the difference between a tidy job and a chewed-up nut that now needs extra attention (and extra time).

The sockets are supplied on a rail, so you’ll need a compatible 3/8-inch drive ratchet to go with them, as this isn’t included in the set.

Why I’d buy it first

  • Solid everyday coverage for typical maintenance jobs
  • Proper AF fit reduces rounded fasteners
  • 3/8-Inch drive is a great all-rounder for engine bay and chassis tasks

TOL202 imperial 8 piece combination spanner set for Austin Healey and Sprite maintenance

2) Imperial 8-Piece Combination Spanner Set

Part Number: TOL202

Sockets are brilliant until they’re not. You’ll still need spanners for carburettor linkages, brackets, awkward nuts and anywhere a socket simply won’t sit square.

This set covers eight popular imperial sizes and comes in a roll, which is handy when you’re working out of a modest garage (or a heroic driveway).

Why it earns its place

  • Covers the “can’t get a socket on it” moments
  • Proper imperial sizing keeps things neat and controlled
  • Easy to keep organised in the supplied roll

TOL104 Gunson timing light with advance feature for setting Austin Healey ignition timing

3) Gunson Timing Light – Advance Feature

Part Number: TOL104

If a Healey runs rough, the carburettors get blamed first. That’s understandable but not always right.

A timing light lets you set ignition timing accurately, which helps starting, idle quality and overall drivability. This one uses an inductive pick-up, so you’re not disconnecting plug leads to use it.

Why beginners should care

  • Timing is your baseline for everything else
  • Stops you adjusting carbs to disguise an ignition issue
  • Helps you diagnose “it feels a bit off” without guessing

TOL103 Gunson Carbalancer tool for balancing SU carburettors on Austin Healey

4) Gunson Carbalancer

Part Number: TOL103

Balancing twin or triple carbs is one of those jobs that sounds mystical until you’ve done it once with the right tool. The Carbalancer makes airflow balance visible, so you can set carbs to pull evenly.

The payoff is a smoother idle, cleaner pickup, and an engine that feels less grumpy in traffic.

Why it’s ideal early on

  • Removes the “by ear” guesswork
  • Helps you get a smooth idle without endless tinkering
  • Especially useful on multi-carb setups

TOL125 Gunson Eezibleed kit for bleeding Austin Healey brakes and clutch

5) Gunson Eezibleed Kit

Part Number: TOL125

Brake and clutch fluid maintenance is basic ownership, and it’s worth doing properly. The Eezibleed uses low air pressure from a spare wheel to push fluid through with a steady, one-way flow, helping prevent air being drawn back into the system.

It also makes bleeding a one-person job, which is excellent news if your “assistant” keeps answering texts mid-pedal-pump.

Before you start: Check that the supplied cap fits your fluid reservoir, follow the manufacturer's pressure instructions and protect surrounding paintwork. Always follow the correct bleeding sequence in your workshop manual. If you're unsure about working on the brakes, seek professional assistance.

Why it’s a smart beginner tool

  • More consistent bleeding with less mess
  • Avoids repeated pedal pumping (and the wear that can bring)
  • Makes routine fluid changes far less of a faff

One simple rule that saves hours

Order of operations matters:

  1. Check the ignition system and timing (TOL104)
  2. Check and balance carburettor airflow (TOL103)
  3. Fine-tune mixture and idle settings according to your workshop manual

Do it the other way round and you can easily “tune around” the real issue, which is how small problems become recurring hobbies.

Final Tips for Your Healey Toolkit

Keep it organised

A tidy kit saves time, while correctly sized tools help prevent damaged nuts and bolts. A tool roll or tool bag keeps everything in one place and is ideal for storing in the car for those just-in-case moments.

Keep a manual close

A good workshop manual for your Big Healey or Sprite & Midget gives you the specs, torque figures, and correct adjustment order, so you’re not relying on guesswork or internet folklore when something feels off.

Build confidence on the basics

Use your tools on routine jobs first: timing checks, carb balance, fluid changes, and simple inspections. Small wins stack up fast, and your Healey will feel better for it.

Frequently Asked Questions

Are these tools suitable for Sprite & Midget owners too?
Yes. The same fundamentals apply: correct timing, balanced carbs (where fitted), tidy hydraulics, and the right imperial hand tools.
Do I need to touch the carbs first if it’s running poorly?
Not usually. Set ignition timing first, then balance the carbs. Carbs are often blamed for issues caused by timing being out.
Is the Carbalancer only for SU carburettors?
It measures airflow, so it’s useful on most multi-carb setups where you want the throttles drawing evenly. SU carbs are simply a common application.
What’s the biggest mistake people make with Eezibleed?
Using too much pressure or rushing the process. The goal is a controlled, steady flow. Keep it low-pressure, work methodically, and protect paintwork from brake fluid.
Why AF sockets and imperial spanners? I’ve already got a metric kit.
Many original fasteners are imperial. Using near-miss metric sizes is a great way to round nuts and bolts. The right sizes make the work cleaner and quicker.
Will the timing light work on a 12V car with electronic ignition?
It’s designed for 12V ignition systems and uses an inductive pick-up, so it typically works well with electronic ignition setups too.
