Please Help.

I`m sure you`ve already looked for vacuum leaks....

I had the same issue with a 750dp on my wagon. It turned out to be the transfer slot on the secondary's. I bought an adjustable 1 to 1 linkage for the carb. While it look to be adjusted correctly on the bench but when I attached the quick disconnect linkage to the carb it pulled the secondary butterflies just enough to cover the transfer slot. I put the original bent metal part back on problem was corrected. Good luck.
