I suspect you mean an MGB.
The stumbling you mention is quite common and a result of using a carb
originally setup for another car, I believe. Every B I have driven with a
Weber of any kind suffered from the malady, even the '80 I bought new and
put a 45 DCOE on. I think you'll find the consensus on this list is to put
the SUs on, and I'd agree.
