Colin Lindsay Posted October 20, 2020 Report Share Posted October 20, 2020 I've had two of these little guys since the year dot; I found them in a drawer this morning and decided to determine which car they came from. I'm pretty certain it's from an SU-fitted engine, but they don't line up with my spare SU carbs at all (although I do have gaskets that match the mounting holes.) If I've measured the dimensions correctly (and I hate mixing metric and Imperial, but needs must in this case) then the hole through the middle is 1 5/8 inches, and the mounting holes are 6.5cm centre to centre. Any idea of what they're off, or how I can find out through application charts or measurements? Link to comment Share on other sites More sharing options...
PeteH Posted January 19, 2021 Report Share Posted January 19, 2021 I could be wrong, but I`ve seen Similar on Dellorto carburetors?. Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted January 19, 2021 Author Report Share Posted January 19, 2021 I've tried all of the SUs that I have, from small to quite large, and they fit none. Didn't try Strombergs, now that I think of it... Might as well pass them on to someone who will use them, if I can work out the application.

Colin Lindsay Posted January 19, 2021 Author Report Share Posted January 19, 2021 Probably... just thinking out loud before bracing the weather towards the garage... bucketing down here as usual. I do have gaskets that match them, but so far not carbs, so it must be something related to a car I've owned before - I suspect the gaskets are left over from a complete engine set.

I don't seem to have a carb that fits, though, despite having quite a few SUs in the garage - I'm going to start another thread to help identify those too, just to pass the time on a rainy day during Lockdown.
