Over the weekend a group of us went on a pootle down to Wilson’s Promontory as we Regionals can, it was a lovely weekend but I think the businesses down there need the return of the Melbournites as we were the sole occupants at the motel.
While we were away during one of the many group male huddles around an open bonnet, it was noted by Colin Cheesman that I had a Grey Fergie tractor carby, this was news to me.
Then I stumbled onto a great article on why this is so, basically in the UK after WW2, old cars were being recommissioned as all the new ones were being sent overseas. A particular problem with late vintage cars was the use of Mazak instead of brass for carburettor bodies. As you probably know Mazak was a really crappy alloy that was used for all sorts of things but it corroded, so this left a whole lot of useful cars with useless carburettors, Zenith who was already making an updraught carby for the grey fergie tractor made a special one for the Austin Seven and that’s the one on my car.
This is the link to the article: http://www.ba7c.org/technicalArticles/carburettorZenith%2024T2.html
From the article I found out the things to look out for with these units, mine is a picture book example of what happens after 70 years of wear, corrosion and neglect.
