Hi Richard

Have you read the page on our website for the 1100/1300 models (https://www.wolseleyregister.co.uk/wolseley-history/blmc/1100-1300/)? It seems that all manual MkII 1300’s should be twin carb, but the auto version remained a single carb. So it all depends on whether the car you are looking at is a manual or an automatic?

I am not an expert on these models, but they are all fairly simple mechanics, based on the old A series engines, so I doubt it would be a difficult job to convert it if you wanted to. Spares are still fairly common, but you do have to look for them. The cars come up on Ebay fairly regularly, being broken up, so you shouldn’t have too much difficulty finding them.

Performance depends on how you intend to drive the car. Most owners now drive their cars fairly steadily, and so I doubt there would be much difference in noticeable acceleration.
