Classic Triumph Spitfire Tuning
I am a Triumph Spitfire engine and carburettor tuning specialist with 47 years of classic car tuning experience. I also work on other classic Triumph models, including the TR7, TR6, TR4 and TR3.
Based near Cambridge, I offer tune-ups for classic Triumph Spitfire cars, combining practical experience with Crypton CMT 2000 diagnostic equipment to help your car start, idle and run as it should.

Specialist tuning for classic Triumph Spitfire cars
The Triumph Spitfire relies on carburettors and a distributor-based ignition system that need correct adjustment to run well. Wear, incorrect settings and carburettor imbalance can all affect starting, idling and overall performance.
A proper tune-up starts with understanding the condition of the engine. I check the ignition system, investigate misfires and assess carburettor operation before carrying out adjustments, so the engine is tuned correctly rather than adjusted blindly.
Tuning can be carried out on a while-you-wait basis, depending on the work required.


Triumph Spitfire SU carburettor tuning
Correct needle and jet condition is essential for peak performance from the Spitfire’s SU carburettors. Worn or incorrect components can cause rough running, hesitation and poor economy.
I can fit, tune and balance SU carburettors, and I can also work with parts you supply.

- Needle and jet condition checks.
- Investigation of uneven running and hesitation.
