When I was using the SOLEX carb on my 1.9 Rekord CIH-engine I had the same problem -> the engine doesn't start after 10 minutes stop at air temp bigger than 18 degrees Celsius . After this I tuned the engine with 2 side draft Solex C40ADDHE and one OP244 KENT CAM ( the rc is around 10:1) . The intake and the exhaust manifolds are hand made ( a lot of work) . Yesterday I installed one heat shield under carbs ->see picture , may be is a usefull idea .
