I’ve been a little busy over the last few days, but here are a few pictures just to keep your interest alive. The crankshaft, camshaft and intermediate magneto drive gear went into the acid bath for a clean up; they are now getting a bath in bicarbonate to neutralise the acid and looking very good already. The barrel still has it’s valves in- both are stuck fast in their guides, so a long soak in the acid will be the order of the day to try to free them up as gently as possible. You can see the effect of the acid bath in the one photo as there is a build up of froth from the reaction with great big flakes of rust floating on the top- I really hope there is something left when I pick it up again!
