Classic Jaguar cars are known for their character, enjoyable driving experience and traditional British engineering. To keep a classic Jaguar running as it should, its carburettors, ignition system and engine settings need to be in suitable condition and correctly adjusted.
With 47 years of classic car tuning experience, I provide specialist tuning and diagnostic services for all classic Jaguar models, including the Mk 1 and Mk 2 Jaguar as well as classic E Type classics with both 6 and 12 cylinder engines.
Using Crypton CMT 2000 equipment alongside practical experience, I can investigate running problems and carry out appropriate tuning adjustments based on your car’s specification and condition.


Many classic Jaguar models use carburettor and distributor-based systems that require a careful, methodical approach to tuning.
I can help investigate common concerns such as uneven idling, difficult starting, hesitation, misfires and poor running. Where appropriate, this includes checking ignition timing, assessing carburettor operation and balancing twin carburettors.
The aim is to identify problems where possible and tune the engine correctly, rather than make adjustments without first understanding its condition.
Carburettor condition and balance can have a significant effect on how a Jaguar engine runs. Twin SU carburettors, in particular, need to work together correctly to provide consistent airflow and fuel delivery.
My tuning work may include:
The work required depends on the model, engine, carburettor type and mechanical condition.

The Crypton CMT 2000 helps investigate ignition performance and engine running concerns. It can provide useful diagnostic information when a classic Jaguar is difficult to start, misfires or does not run smoothly.
Where faults are identified, I can discuss the findings and any additional repairs or replacement parts that may be required before the engine can be tuned accurately.
My base in the PE14 9PJ postcode area offers a convenient option for MG owners in Cambridge, Cambridgeshire and nearby areas.
If you own an classic Jaguar, contact me with the model, year and engine details. I can discuss the symptoms and suitable appointment options.

Keep your MG enjoyable to drive with specialist tuning and diagnostic support.
