I'm refurbish a pair of solex 32-34 pdsit-2 & 3 that came with my 2l type 4 engine (which was out of the van when I bought it). Both carbs are missing the hot idle valve and screw/lock washer. I was just wondering if they were removed by the PO as just not necessary or if I need to get some replacements. If I do need them, where's the best place? (Couldn't find anything on eBay). Thanks
