This 998cc Mini Mayfair came to me for some repairs and a tune.
After completing the minor repair work as well as changing out the exhaust manifold gastket, I turned my attention to tuning the engine.
The car drove fairly well to my garage and I thought that it would be needing only minor needle fuel profiling however I ended up replacing all of the ignition system including a new recurved distributor with my Fast Road curve.
I also did a full rebuild on the HS4 waxstat carb as the throttle shaft bushings were very worn and the idle mixture was unstable.
With the new ignition system installed and the rebuilt carb, I was able to start tuning the needle.
I got lucky with my first needle choice AEM that gave the best steady speed fueling. I then had to adjust the top end and full throttle fueling.
The car was running very well and we then went on a 600 mile trip to the Mini Meet in South Dakota.
The car performed excellently and averaged 45mpg for the trip with one leg of the trip at 50mpg!!
