I had a similar problem w/ my 77 B with a Weber DGV and CRANE ignition. Check
your timing and disconnect the vacuum advance. According to a guy in my club,
the Crane does a good job of advancing the ignition and the vacuum advance
makes the engine sputter when the Crane is installed. I guess this is true as
my car has not sputtered since.
Also, check your fuel pump.
