Challenge Progress

The carbs arrived a while ago at the Harpers' workshop and one half was subjected to our standard cleaning process for corroded parts. There was some significant problems associated with long term neglect; the choke shaft was seized solid in the bodies, both float valves were gummed into their seats and the end of the throttle cable outer was badly stuck in it's holder on the top brace.
Apart from the issues present, the float bowls were also missing, we suspect they had been discarded due to excessively poor condition.
After the cleaning process particular attention was given to rinsing and drying prior to reassembly, the change was astonishing and much rust was removed by the new solution; some brass parts that had also collected soft Verdigrise-like deposits had also been cleaned. The effects on brass were very good although surface colouring remained.
We hope to photograph the set once they have been reassembled to show the clean and dirty parts, the intention being to somehow seal the dirty carb with lacquer or similar and mount the pair for display to customers.
