Maybe it is the fact that I have been playing with a lot of carburetors recently – both SU and Zenith-Stromberg. Or perhaps it is the fact that I had a friend ask how such a simple design could work. They literally stared at me in dumbfounded amazement when I explained the basic principles by which our carbs work. But, whatever the case, there are a lot of people who consider carburetors a bit of black magic, and I thought this video from Moss might help sort that out.
To that end, our Video of the Week (VotW) is “Side Draft Carburetors and How They Work” from Moss Motors. Now in addition to providing a wealth of great parts, Moss also does its part (get it?) to keep our cars on the road by producing a series of videos on everything from carburetor or ignition operation to how to install suspension pieces. They literally have hundreds of quality videos on Youtube. These videos, along with those from the likes of John Twist at University Motors, go a long way to getting folks over the learning curve with old cars.
If you want to delve even further into the fuel intake subject, I highly recommend “SU Carburetters Tuning Tips And Techniques“. This book covers not only the carburetors but the iconic and sometimes irksome SU fuel pumps as well. If your main interest is carburetors then “Weber Carburetor Manual: Including Zenith, Stromberg and SU Carburetors” is a good one. It covers the three most popular types of carbs on our cars with plenty of illustrations – you will forgo the fuel pump data though.
Finally, don’t forget to check out Burlen LTD. They have the license on SU these days and continue to supply parts and complete units for a wide range of applications.
