My favourite among the various penetrating products is the Australian made INOX I have found it will work where others fail. Perhaps it is because of the one claim among the list of properties shown on the label that I have not seen on any of the similar products. No prizes but who can spot the extra benefit.

Kosher or not Inox has helped considerably in dismantling the Renault Carburettor. I have not managed to take the lower brass section completely down to its component pieces. I am still working on the upper Aluminium half. The main problem is with the sliding venturi which acts to rechen the mixture to assist in cols starts. So far after two days alternative soaking and heating managed to move it about 1/8th of an inch so I guess that it is a case of just a little at a time. Due to the totally irreplacable nature of the carburretor I am having to work in virtual kid gloves.

Well! Now that I have finally managed to move the sliding section or perhaps I should have said the frozen section, I can now throw the lot in the bin!

I can now visulaise what has been going on over a number of years. The motor had been standing outside in the open with the spark-plugs removed. Every time it rained the cylinders filled with water then the water eventually overflowed through any valves that happened to be open. Where there was an inlet valve open the water drained down through the inlet mainfold and into the very convoluted, up-draft, carburettor welling up on top of the aluminium choke section. Left for several years like this the aluminium has corroded to a point where the internals or the carburettor had virtually welded themselves together. The internals are now at a stage where it is impossible to repair the damage done.

Back to square one! as the French would say, Merde!

Looking at the illustration; the section in the centre where the main jet protudes into the venturi was completely blocked with debris blocking the exit for any water so that over time it had welled up in the throat of the carb and presto corrosion started with disasterous results.
