These cars are criminally underrated. Congratulations on picking one up. If you can get past the rust issues, it will quickly become one of your (and your wife's) favorite cars. You have a lot of studying up to do on SU carburetors. If you haven't already, get yourself a Moss Motors parts catalog. The exploded diagrams in it will be invaluable to you. Don't expect the car to run well until you replace all the rubber components in the carburetors, the dashpots have been oiled and they have been adjusted correctly. After that, the majority of the running problems you encounter will be caused by the distributor. Electronic ignition makes things a lot easier. Thanks for posting.
I was playing with mine today, its been sitting too long, my paint job faded and the brakes have failed, thanks for reminding me how it felt when i first got it
