Vaccum advance problem

I installed the MC 2150 carb and the msd street fire box on my 4.2 automatic 89 Sahara. After the install everything runs ok and I did retime it, but it will not run with the VA hooked up. It acts as if it is retarding the timing rather than advancing. Anyone have any ideas? Thanks for any help
