I run a 32/36 but it is on an A12 with ported heads, bigger valves, GX cam and extractors , plus it only gets track use. The idle is ok and the carb works well......I also like the much maligned SU types and had no problems. I only switched out the SU type because I was doing a tarmac rally which required the car to get a smog check to be road legal.
Now on a Plymouth Arrow (Mitsubishi) I had a 32/36 and it never really idled great, ran fine but idle was eratic. In the states used 32/36's in good order can be had for $50.
