1991 1.6 Driver - Weber 32/34

Hi, I recently bought a MK2 1.6 Driver which has a "Weber" carb which I have self-ID'd as a 32/34 but don't know enough to be certain. The car was having high idle issues before I purchased (1200-1500rpm) and seeing as I had never owned a MK2, would be a great idea to get into it. Here's what I found at the base of the carb after removing the filter box.

I am assuming the piece that has cracked (and most likely the cause of my vac leak) is an adapter mount. However, when I look for a replacement online, the mount that shows up looks nothing like the one which is broken but looks more like a "FoMoCo VV" mount. Could this be why it has broken in the first place and does anybody have any more insight on whether I should even continue using the carb at all, as I could probably convert the whole car into an injection clone for the price of a new Weber - if it is not affordable or recommended to repair. Thanks for any insight.  8)

If anything has broken, its most likely to be the rubber mount for the carb, which tend to split.  You can get replacements off ebay.  I prefer the Febi Bilstein one because the quality is much better.  All the parts for the carb can be bought from Web con.  https://www.webcon.co.uk/  However, I dont think a high idle would be caused by a vacuum leak.  In my experience a vacuum leak causes a car to idle lower and stall, because the extra air leans out the mixture.  Have you tried adjusting the idle?  You do this by adjusting the throttle stop which is easy to do.

In the image I posted, I showed where the metal mount meets the manifold with the rubber on top of that. The rubber looks OK but the mount is very badly split and warped. Upon searching for replacement mounts I couldn't find one that looks like my broken one, So I referred to the image of a brand new Weber 32/34 MK2 kit and the mount that I'm supposed to have looks nothing like mine... just a £90 replacement  :-[

The part that is split in that photo, is the rubber mount.  The rubber mount bolts straight onto the inlet manifold.  It looks like someone has painted over the bottom half of the rubber mount, presumably to paint the manifold.  Once you remove the carb you will be able to see it properly.  I recommend the Febi rubber mount, as it puts up with the ethanol in modern fuel better.  However, I dont think its the cause of your idle issue.

It is the right item. I have the same carb, and bought that rubber mount myself. The adaptor plate is designed to convert the Weber to fit the original rubber mount.
