Though I prefer the SU, I agree with George here that if you can't get it going correctly, the Weber 32/36 works. Works well even!
The DCOE is a real screamer, but takes a lot of knowledge to get it set up right. (This is well documented in the Vizard book)
The SU is easy enough, but I always hated the needle "numbering" system. There is fortunately a program WinSU to help with that choice. It costs a bit of money. Other than that the SU is a wonderful carb. Flexible enough for different operating conditions. Few moving parts for durability. Reasonably good with mixture control (good economy). Actually the biggest problem is the siamese ports on the head.
Actually I had a pair of 45 DCOEs on my Volvo Amazon. It took a month to adjust properly with my limited equipment. In the end it was really perfect. Good economy (25mpg), started easily when cold, no flat spots, extreemly powerful etc. Until one day I broke the gearbox, driveshaft and differential - all at one time. It was too hot and the clutch was too unforgiving. Now I have the single 1.75 Stromberg back on it.
