Update report - September 15, 2018

I am pleased to report that we have now completed this very challenging engine rebuild. The cylinder head was very badly corroded, both on the deck surface and internally. It really was borderline whether we could save this particular head, but fortunately we were able to call upon the services of Jake Hill in the CJ Coachworks who saved the day with his world class welding skills. We have also fully rebuilt the SU carbs and will be running the engine on the test stand in the next few days.
